Command Error Delay
0 to 300
This parameter specifies the number of 100 millisecond intervals to turn off a
command in the error list after an error is recognized for the command. If this
parameter is set to 0, there will be no delay.
MBAP Port Override
Y ES or N O
If this parameter is set to Y ES , all messages generated by the Client driver will be
MBAP format messages to all Service Port values.
If this parameter is set to N O (default value), or is omitted from the configuration
file, all messages sent to Service Port 502 will be MBAP format messages, and
all other Service Ports values will use the encapsulated Modbus message format
(MNET).
Each Client is configured independently in the configuration file.
This parameter applies to firmware version 1.05 and above. For downward
compatibility, you may omit this parameter from the Client's configuration.
2.2.7 MNET Client x Commands
The MNET Client x Commands section of the configuration sets the Modbus
TCP/IP Client command list. This command list polls Modbus TCP/IP server
devices attached to the Modbus TCP/IP Client port. The module supports
numerous commands. This permits the module to interface with a wide variety of
Modbus TCP/IP protocol devices.
The function codes used for each command are those specified in the Modbus
protocol. Each command list record has the same format. The first part of the
record contains the information relating to the MVI56E-MNETC communication
module, and the second part contains information required to interface to the
Modbus TCP/IP server device.
