MODBUS ADDRESS FROM/TO
Configuring these fields sets up the range of Modbus slave addresses that will be
forwarded to the IP address (that you will configure in the next step).
The prompt:
Modbus addr from (1)
indicates that no slave addresses have been
added to the list so far. If other slave addresses have already been configured, the
number will reflect the first available slave address number.
37.
Press
Enter
to accept
(1)
as the first slave address number, or type
in the number you prefer. After you press Enter, the
Modbus
Address To
prompt appears.
38.
Type in an slave address number that reflects the range of slaves
that will be found at the IP address that will be entered in the next
step. When you press
Enter the Slave IP address
prompt appears.
SLAVE IP ADDRESS
Type in the four octets of the IP address of the slaves being addressed.
If you configure the last octet as 000 the MES1A/B will use the Slave
Address/Unit ID of the slave as part of the IP address. This allows a
Modbus/RTU master (connected through the MES1A/B) to access up to
255 remote Modbus TCP slaves.
If you configure the last octet for a number between 1 and 254, all slave
polls in this group will be sent to the same IP address.
