Each time a process begins, I use an EoS (execute on server) method to write a
process variable (an objet) in the twin. As the twin is also the process that
executes the trigger, it will read user from that variable.
3 methods:
a) on startup call User_infosSet
set some properties in c_object <>userInfo_o on client side (user PK, name,
login, machine, ip address, etc.)
b) when a client process begins, always call User_infosSet_srv
this is the EoS method, it receives <>userInfo_o as $1 and makes a copy of it
in a c_object userInfo_o on server side
c) when needed (client side, trigger…) call User_infosGet (property)
get some property in the object,
case of
: client side
read property in <>userInfo_o
: server side (twin)
read property in userInfo_o
Know issue:
- one more process variable on server
- never forget b) (as I sometimes do)
Besides that, the trigger knows the user.
I can send the code if needed.
