IODDTs

Overview

The IODDTs are predefined and contain language objects of inputs/outputs belonging to the channel of the module.

The BMXERT1604T/H module has the following associated IODDTs:

T_ERT_CNT: For channels configured as counter
T_ERT_TS_MOD: For channel 0 with time stamping function (with module status bits included)
T_ERT_TS: For channels 1...15 which are configured as time stamping
T_DIS_IN_GEN: For channels configured as discrete input or channels 1...15 configured as time stamping

As any Modicon X80 module, the BMXERT1604T/H module also has a T_GEN_MOD IODDT associated.

T_ERT_CNT, T_ERT_TS_MOD, and T_ERT_TS are specific IODDT for BMXERT1604T/H module while T_DIS_IN_GEN is a generic IODDT for all discrete input.
