Then you'd only need to specify how many of each you want to access, along with the base address. It gets more complicated if you need to allow access to registers/coils in multiple discontiguous ranges. There's also a problem with multi-register values. Some devices can handle 32-bit values, which are generally composed of two 16-bit %Rxx values. I'm not sure if the spec tells you to use a certain endian-ness, so it may be necessary to be able to specify that as well. This is why I was thinking about a higher level spec for specific devices (ideally with a low-level core that's at least from common source code, and at best a single shared module). It would be much more readable in HAL to have a modbus.0.vfd.0.spindle-speed pin rather than having something like the inverse of a scale block to convert from float to whatever integer units the VFD uses, then possibly to split that into two 16-bit words for connection to modbus.1.register001 and modbus.1.register002. It would also be possible now that I think of it, to have a VFD module that converts from engineering units to whatever registers and coils the modbus interface provides. The downside is that you end up with a lot of HAL connections that aren't really useful, and can cause major problems if they're screwed up (imagine the oops of swapping the high and low words of a spindle speed, for example). Opps, I changed my mind. The simplicity of only thinking about coils and registers just moved the necessary complexity to another area. Just like all other hardware, I think, a file is needed to interface the hardware's features to EMC, There are just too many variables to try to make a generic interface. So my latest thinking is to make a component, SJ200-mb-rtu with pins and parameters for the features I want to interface with EMC like SJ200-mb-rtu.0.frequency-in, SJ200-mb-rtu.0.run, etc. The SJ200 component would know that to write to a register, we start with a Modbus address number, function code of 0x06 (register write), 0x00 ( reg. addr. high, 2 bytes), 0x01 (reg. addr. low, 2 bytes), and pin value (2 bytes). This stream would then be placed in a message buffer for the Modbus program handling the desired serial port, Modbus would add a CRC to the end and send it. The buffer is a mystery to me. I think I saw in the HAL documentation that pins could be arrays. I didn't want to have any device dependent features in the Modbus RTU component. I was hoping that that would be up to mixing other components to get the data into the proper form. The Modbus RTU component would only handle assembling the packet, managing the communications protocol, and handling communications errors. I am using the my VFD manual as a guide, and all of its registers are eight bit. For 16 bit parameters, it uses two register addresses and no floating point, such as: Func- | Name | R | Description | Reg- | Ra- | Res- tion | | / | | ister | nge | olu- I was wrong here, the SJ200 uses 16 bit registers. The Modbus standard indicates a frame as: Slave | Function | Data | CRC Address | Code || Check -- 1 byte | 1 byte | 0 to 252 bytes | 2 bytes So, for other Modbus devices the registers could be any number of bytes long up to 252 bytes.

Re: [Emc-users] RFC, Modbus Spec.
Hi, I don't know a lot about how EMC works, but I do know quite a lot about Modbus. Modbus data basically consists of 2 data types, bits (discretes an coils) and 16 bit words (input, and holding registers) There are also special representations of multiple registers (flloating point etc). The interface is designed so that data is transferred at periodic rates and can be looked at as a shared memory interface. The modbus interface transferes the data between the master and slaves at a rate required by the applications using the data. THerefore one option for an interface scheme is to setup the Modbus master with a schedule of transactions to perform such as; Slave_id, operation, number of items, rate The slave_id is the subaddress of the slave. The operation is the modbus command such as read_holding register, write coils, etc, The number of items is how many registers, discretes are to be read or written. The rate is the periodic rate that the operation is performed, 25Hz, 50Hz etc. For each one of the transactions that have been set up, there will been to be a data array for holding the data that is read or written. It is this array that EMC interacts with. With the above you have a schedule of events to be performed. This is independent of how EMC is going to manipulate the data. As EMC interacts with the data array, the data is transferred to/from the slave independently. If nothing else, it may be food for further thought. Cheers, Peter.

The index-enable HAL pin is bidirectional - you need to set it true, then the driver will set it false (and reset the counter) on the next index pulse. If index-enable is false, the driver does nothing at all when it sees an index pulse. The pulse shows as about 2 mS wide at 4 ipm so it is there. Looks good at both Z and not-Z on the encoder plug to the breakout board. Comments, ideas, experience, etc. would be appreciated.

posted your introduction pdf to my site Thank you! I haven't been able to track down who did the video recording during my talk. Does anyone know? If we can find that tape, peel the audio track off, and put it near the PDFs, that would be a good addition. Why the kid's finger in disrepair? Fortunately, that's not her finger.

[Emc-users] classicladder V 7.124 in cvs
Greetings. I'm just annoncing That I have uploaded a working (HAL asized ) version of Marc's Classicladder version 7.124. This is NOT a finished, stable, well-tested version. I'm looking for testers and opinions. In particular MODBUS in enabled in this version but I don't have anyway to test it yet. It also has a nice status bar that gives you info about elements that you click on to. I will modify this to give HAL signal names in the future. There is a new timer element that is easier to use and upholds the iec standard. TIMER_IEC jump coils and call coils work better and do error checking for endless loops. (these are like goto and gosub calls) It loads the same as before and should be inter-changeable with out changes nor should old ladder programs, though more testing is needed. I will start a Wikki page for it soon. It is available by downloading emc with this tag: cl_v7124_branch Cheers Chris Morley _ - This SF.net email is sponsored by: Microsoft Defy all challenges.

Re: [Emc-users] Dual Linux EMC Installation on Dual HDDs

I don't know what system Paul is getting 1000+ warnings or errors on. The page at http://www.linuxcnc.org/compile_farm/ has links to build logs for several systems, including Paul's BDI-4.51. Breezy with stock non-RT kernel: 0 errors 1 warning from configure 4 warnings related to man pages Breezy with RT kernel: 0 errors 1 warning from configure 4 warnings related to man pages BDI-4.51 0 errors 1 warning from configure 34 warnings during MODPOST 4 warnings related to man pages All of the above logs are from incremental builds, full builds might have more warnings. Full builds will automatically happen in 12 hours or less, or when I get home and manually force a full build. Feel free to check the results yourself once the complete builds are done. The compile farm webpages are intended mostly to help developers, but all of the data there is completely public. The last system is Dapper, with a RT kernel, and it is a complete build. Unfortunately that system hasn't done a build since November, I've had that computer turned off for a while. I'll turn it on and kick off a build tonight. In any case, a complete build on Dapper had: 0 errors 1 warning from configure 2 warnings about redefined macros 7 warnings related to man pages Errors in EMC2 builds are rare - anything that causes a build to fail on the compile farm automatically sends a message to the emc-developers list, and to the #emc-devel IRC channel. People notice those messages, and build errors get fixed fast. Warnings don't get automatically announced, and I admit we should probably review the logs more often and fix as many warnings as possible. Thanks for bring this to our attention Paul.

[Emc-users] Pluto-P
Friends, I am looking for feedback from Pluto-P users... I am working on a breakout board for the Pluto-P, more-or-less a daughter board to bring the pins out to screw clamps with buffers or pull-ups where needed. I'd like to see a list of the pinout of the Pluto-P that you are currently using. I'll send anyone who contributes to this a free Pluto-p professionally built breakout board. Takers?

Re: [Emc-users] wanted: motion delay with spindle start/stop
Thomas Fritz wrote: I remember from a previous incarnation of EMC1 a parameter for adding a delay when starting or stopping the spindle, to wait for it to spin-up, usually. What would the current approach be to implement something like that in EMC2? G4? Or do you want to put the delay in the machine configuration? On the mazak we connected the spindle VFD's at-speed output to EMC's feed-hold input (inverted of course), so the machine won't move until the spindle gets up to speed. I'm not sure thats the right approach, but it worked. Some other things, like tool-change, use a request/reply handshaking model, where one HAL pin tells the external stuff to do something, and another pin tells EMC that its done. I suppose we could do something like that for spindle run, and by default loop the request right back to the response so the existing behavior doesn't change. Then you could add a delay or other interlock if you want it. Regards, John Kasunich - This SF.net email is sponsored by: Microsoft Defy all challenges.

Re: [Emc-users] Touch up screen device -who is mfg.
Hi Stuart. I want to buy Keytec model KTMT-1921-USB what is 19021 inch. is this good model? Will it work with Lunix? Any final recomedation before i buy it? i assume that bigget screen will work with smaller monitor. Am i right on last one? Thank you Thank you Aram Aram, The problem with using a monitor larger than the touch screen is the Keytec configuration routine. It has you touch the lower left corner, then the center of the monitor, then the upper right corner. With the monitor bigger than the touch screen you will not be able to touch the corners. This will not allow the configuration of the touch screen. thanks Stuart - This SF.net email is sponsored by: Microsoft Defy all challenges.
