Station Address
= The configured station address set by the user
DOut Len
is the total number of output bytes with the S1, S2 and S3 values being
pointers to the 3 output buffers in the SPC3 chip.
DIn Len
is the total number of input bytes with the S1, S2 and S3 values being pointers
to the 3 input buffers in the SPC3 chip.
Diag1Len
should always be 6 to represent the minimal number of diagnostic bytes and
S= pointer in SPC3 chip to this data.
Diag2Len
is the extended diagnostic buffer length and S is a pointer to this data in the
SPC3 chip.
Aux1 Len:
(see SPC3 specification) and S is a pointer to this data in the SPC3 chip.
Aux2 Len:
(see SPC3 specification) and S is a pointer to this data in the SPC3 chip.
SSA Len
is not used and should be 0 and its pointer S is N/A.
Param Len
= is the length of the parameter data for the slave with S as the pointer in the
SPC3 chip to the data.
Cfg Len
is the configuration length for the slave with S as the pointer.
RCfg len
is that received from the master with S as the pointer.
Ident
is the PROFIBUS identification number for the module.
FDL SAP last PTR
is the end of all the PDPS data in the SPC3 chip. A value greater
than 0xFF indicates a memory overflow problem.
Comm Failure mode
is that from the configuration file as is the swapping of input and
output data.
Viewing PROFIBUS Status
Enable State
Indicates the initialized state of the MVI46-PDPS module.
0 = Module is not initialized
1 = Module is initialized
Module State
Indicates the current state of the MVI46-PDPS module.
0 = Normal Operation
1 = Shutdown
2 = File Transfer
3 = SPC3 ASIC problem
4 = Not in data exchange
