Write Register Start
0 to 4999
This parameter specifies the starting register in the module where the data will be
transferred from the processor to the module. Valid range for this parameter is 0
to 4999.
Write Register Count
0 to 5000
This parameter specifies the number of registers to transfer from the processor to
the module. Valid entry for this parameter is 0 to 5000 words.
Failure Flag Count
0 through 65535
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 (Type 2).
Pass-Through Mode
0, 1, 2 or 3
This parameter specifies the pass-through mode for write messages received by
the MNET and MBAP server ports.
ƒ If the parameter is set to 0, all write messages will be placed in the module’s
virtual database.
ƒ If a value of 1 is entered, write messages received will be sent to the
processor as unformatted messages.
ƒ If a value of 2 is entered, write messages received will be sent to the
processor as formatted messages.
ƒ If a value of 3 is entered, write messages received will be sent to the
processor with the bytes swapped in a formatted message.
