Starting register location in virtual Modbus database for the error/status table. If a value of -1 is entered, the error/status data will not be placed in the database. All other valid values determine the starting location of the data. This data area includes the module version information and all server error/status data. M1 Write Size 0 to 5000 words This parameter limits the M1 data transferred from the processor to the module. This parameter is only available in versions 1.31 and newer. The module application automatically adjusts the size to an even 50-word boundary as this is the minimum data transfer size for the application. For example, a value of 199 would automatically be adjusted to 200. This feature improves the transfer of data from the processor to the module.

This parameter specifies

 the number of successive transfer errors that must occur before the communication ports are shut down. If the parameter is set to 0, the communication ports will continue to operate under all conditions. If the value is set larger than 0 (1 to 65535), communications will cease if the specified number of failures occur. Initialize Output Data Yes or No The Initialize Output Data parameter determines if the output data for the module should be initialized with values from the processor. If the value is set to N, the output data will be initialized to 0. If the value is set to Y during initialization, the module will invert (for this scan only) all backplane commands

[Static ARP Table]

 The Static ARP Table defines a list of static IP addresses that the module will use when an ARP (Address Resolution Protocol) is required. The module will accept up to 40 static IP/MAC address data sets. Use the Static ARP table to reduce the amount of network traffic by specifying IP addresses and their associated MAC (hardware) addresses that the MVI46- MNET module will be communicating with regularly. Important: If the device in the field is changed, this table must be updated to contain the new MAC address for the device and downloaded to the module. If the MAC is not changed, no communications with the module will be provided.
