Modbus TCP Port 2 EMOD > 1
PMOTCP1 PMU Output 1 TCP/IP (Local)
Port Number
PMOTS1 := TCP, UDP_T, or UDP_U
PMOTCP2 PMU Output 2 TCP/IP (Local)
Port Number
PMOTS2 := TCP, UDP_T, or UDP_U
DNPNUM DNPTCP and UDP Port EDNP > 0

MODNUM1 and MODNUM2 can have the same port number. The relay displays an error
message if this number matches with the port numbers of other protocols.
