INU modules#

Starting from version 10.38 it is possible to connect INU I/O modules to Fx sub station. Port type is MODBUS but same port may communicate only with INU I/O modules.

Baudrate is 19200.

Supported module types are PSR2000 series AI/AO and DI/DO modules and newer DIN rail installed AI/AO and DI/DO modules.

Each INU module is programmed as two modules in Fx station.

Address of AI and DI modules is always in range 1..16 and 16 is added to address of corresponding AO and DO module.

4 AO points must be defined into PSR2000 series AI/AO modules and 8 for newer modules..

Example.

  • INU AI/AO module at address 5 and INU DI/DO module at address 10 is connected to port.

  • Following modules must be programmed to Fx

    • INU_AI at address 5

    • INU_AO at address 21 (5+16)

    • INU_DI at address 10

    • INU_DO at address 26 (10+16)

This feature has separate fee and it must be activated before use.
