A-1-6 Clear Error Explicit Message Example Using CMND(490)
With an EtherNet/IP Unit, a CMND(490) instruction in the PLC CPU Unit’s ladder diagram program can
send explicit messages to a Slave Terminal.
The clear error service code (0x32 hex) is sent to the Slave Terminal at IP address 192.168.250.1,
using the CIP UCMM MESSAGE SEND command, 2810. The network number assigned to the Ether-
Net/IP network is 1. The IP address and node number of the EtherNet/IP Unit is 33.
The command data is stored in the DM Area starting at DM01000, and the response data is stored in
the DM Area starting at D02000. If the command ends with an error, the end code is stored in D00006
and command transmission is retried.
