Hello,
I try to communicate my PI2 with OTB SCHNEIDER TCP / IP Modbus card.

OTB config:
1st module: OTB 1E0DM9LP - V2.xx
2nd module: OTB TM2AMI4LT - V2.xx

Config CoDeSys:
Modbus_TCP_slave_1
IP: 192.168.1.11
Unit_ID: 127
reading code 23:
read address: 2000
Writing address: 2100

Modbus_TCP_slave_2
IP: 192.168.1.11
Unit_ID: 1
code reading 3:
read address: 2001

When I want to write an output map (2100) no problem
The problem is that I can not at all to read the analog channel 2001

In Advantys,
the first card is on UNIT_ID: 127 and the next is on UNIT_ID: 1

Does someone has already tested CoDeSys 3.5 SP6 Patch 1 with material SCHNEIDER OTB?
What way can we configure OTB cards SCHNEIDER CoDeSys ??????

Thank you for your help
Ludo

Hi,
I finally found the solution.
As the cards do not have the same ID_unit , we must separate the reading frames
