Precautions for Correct Use
The Register No. and read/write data are the same as those for Modbus communication. For
these settings, refer to Section 6-8 Modbus Communication (Modbus-RTU) Data List of the
MX2 User's Manual (Cat. No. I570) and 8-5 Modbus Communication Register Number List of
the RX User's Manual (Cat. No. I578).
The error codes for the Special IO operation are listed below.
Special Remote Input Error Codes
Precautions for Correct Use
Precautions for Correct Use
If a Special I/O read/write error occurs, the most significant bit (word address n, bit 7) of the
Function Code turns ON. Prepare a program that starts error processing from this bit on the
host.
In Modbus communication, the MX2/RX-series inverters set control input, status monitor, or other bit
information as coil information. This means that you cannot set/check data by reading/writing from/to
communications registers.
Use the following registers provided to enable reading/writing of input and output bit information.
Register No. 1F01 hex for CompoNet output (Inverter control input)
