SW1-31 ECS1737-3  Control module

This parameter defines the start register for floating-point data in the internal database. This parameter is used only if the Enron-Daniels is enabled. For example, if the Enron-Daniels Float Offset value is set to 3000 and the EnronDaniels Float Start parameter is set to 7000, data requests for register 7000 will use the internal Modbus register 3000.This parameter specifies the number of seconds to wait for an ARP reply after a request is issued.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.If this parameter is set to YES, all messages generated by the Client driver will be MBAP format messages to all Service Port values.

If this parameter is set to NO (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.

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 MVI46-MNETC communication module, and the second part contains information required to interface to the Modbus TCP/IP server device
