Programming Example 2: ME1DA6HAI-Q used in Remote I/O Network

5 – 14

● In the event of an error, the error code shall be displayed in BCD format.

The error code shall be reset after removal of the cause.

● If one of the connected HART device is malfunctioning, error processing is performed.

5.3.1 Before creating a program

Before creating the program, perform the steps described in section 5.2.1.

The PLC parameters for a remote I/O module can be set in the same manner as for the CPU module.

However, for a remote I/O station only the required items can be set.

To write the intelligent function module parameters, set the target remote I/O station from the Online

menu (Transfer setup) on GX Developer or GX IEC Developer. They can be written by:

– Directly connecting GX (IEC) Developer to the remote I/O station.

– Connecting GX (IEC) Developer to another device such as a CPU module and passing through the

network.
