Write Register Count
0 to 10000
The Write Register Count parameter specifies the size of the Write Data area of
module memory and the number of registers to transfer from the processor to
this memory area, up to a maximum value of 10,000 words.
Note: Total Read Register Count and Write Register Count cannot exceed 10,000 total registers.
Read Data and Write Data Areas must be configured to occupy separate address ranges in
module memory and should not be allowed to overlap.
Failure Flag Count
If this value is greater than zero the protocol communication will be interrupted
once a backplane failure is detected, or communication with the processor fails.
A value of zero will disable this feature.
Initialize Output Data
0 = No, 1 = Yes
This parameter is used to determine if the output data for the module should be
initialized with values from the processor. If the value is set to 0, the output data
will be initialized to 0. If the value is set to 1, the data will be initialized with data
from the processor. Use of this option requires associated ladder logic to pass
the data from the processor to the module.
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.
If the parameter is set to 0, all write messages will be placed in the module’s
virtual database.
If a value of 1 is entered, write messages received will be sent to the
processor as unformatted messages.
If a value of 2 is entered, write messages received will be sent to the
processor as formatted messages.
If a value of 3 is entered, write messages received will be sent to the
processor with the bytes swapped in a formatted message.
Note: To take advantage of the new features described above, your MVI56E-
MNETC/MNETCXT module needs to have firmware version 3.01 or higher, and
your MVI56E-MNETC/MNETCXT Add-On Instruction needs to be version 1.8 or
higher. Earlier versions have no server capabilities and support only up to 5000
user database registers.
