Revision: 2.0

In groov Build, Modbus/TCP device slave IDs are not allowed above 247


Applies To:

GROOV-AR1-BASE
GROOV-SVR-WIN-BASE
GROOV-AR1
GROOV-AR1-SNAP
GROOV-SVR-WIN
GROOV-SVR-WIN-SNAP
GROOV-AT1
GROOV-AT1-SNAP

Versions Affected:

Problem affects: All versions through R3.0a

Resolved In Version:

R3.0b


Symptoms:

When you configure a Modbus/TCP device, the slave ID value allowed is 0-247 rather than the usual 0-255.

Workaround:

Depending on your Modbus device, the slave ID may be unnecessary. When you use Modbus/TPC, the IP address is the primary identifier for communication. Unless your Modbus/TCP device requires the slave ID, leave it at zero (the default for this field).

Resolution:

Opto 22 has resolved this issue.
