Note: Communications error details are stored until an fault reset is input (you can also reset while the Unit is operating).

Broadcast Data

The following table shows the broadcast data. You can also write this data.

Note: Bit signals not defined in the broadcast operation signals use local node data signals continuously.

ENTER Command

When writing parameters to the MxC from the PLC using MEMOBUS communications, the parameters are
temporarily stored in the parameter data area in the MxC. To enable these parameters in the parameter data
area, use the ENTER Command.

There are two types of ENTER Commands: ENTER Commands that enable parameter data in RAM, and
ENTER Commands that write data to EEPROM (non-volatile memory) in the MxC at the same time as
enabling data in RAM.

The following table shows the ENTER Command data. ENTER Command data can only be written.

The ENTER Command is enabled by writing 0 to register number 0900H or 0901H.

Write parameter data to EEPROM

0910H

Parameter data is not written to EEPROM, but refreshed in RAM only.

INFO

EEPROM can be written to from MxC a maximum of 100,000 times. Refrain from writing excessively to the
EEPROM using the Enter Commands (0900H).
The ENTER Command registers are write-only. Consequently, if reading these registers, the register address
will become invalid (Error code: 02H).

Register No.
