Precautions
• For software versions for which default gateway can be set, refer to the following:
(Page 299 Added and Changed Functions)
• CH2 cannot be set for RD55UP06-V-BZ11, RD55UP06-V-BZ13, and RD55UP06-V-BZ15 because they have only one
Ethernet port.
• Do not configure the same IP address between the storage destination register of CH1 and the storage destination register
of CH2.
• When configuring an invalid IP address for a storage destination register, the IP address of a SECS/GEM communication
software pre-installed model module cannot be changed. The value of the storage destination register is changed to that of
the current IP address.
• If changing an IP address fails, an event log will be registered in the event history. Check the event history and
troubleshooting by symptoms and then take corrective actions. (Page 271 Troubleshooting by Symptom)
