2 Installing the NB Unit and Connecting Peripheral Devices
2-42
NB-series Programmable Terminals Setup Manual(V107)
Because the port number of NB is dynamic, the user doesn’t need to set it during the communications
through the FINS/UDP protocol. But user needs to set the UDP parameters at the Host side of OMRON
PLC in the CX-Programmer referring to the following limitations.
Take the settings of CJ1W-ETN21 as example:
The limitations are as follows:
1. Do not check the “Auto (Static)” option in the [Conversion] check box.
2. Do not check the “Destination IP is Not changed dyn:” in the [FINS/UDP Option] check box.
3. Only the “Destination IP is changed dynamic:” can be checked in the [FINS/UDP Option] check box
after either of “Auto (dynamic)”, “Combined” and “IP address table” is checked in the [Conversion]
check box. When insert the IP address into the [IP Address Table] after the “IP address table” or
“Combined” is checked, do not make the Node ID of NB into it. *1
*1 If the Node ID of NB is placed into the [IP Address Table], the system will require the NB to use the
same port with the PLC, and “PLC response error” information will appear on NB.
The prompts for possible errors occurred to NB when FINS/UDP protocol is adopted are described as
follows:
“PLC Response Error”: Response to the abnormal information caused by the Read/Write command to
PLC.
“PLC No Response: xx-xx-x”: No response is made by PLC and xx-xx-x represents HMI No.-Node ID
of PLC-Port Number.
