Description of the blocks
4.2 Diagnostics block MMDiag
SIMOCODE pro PCS 7 Library V9.0

4.2.2
Acyclic reading of data record 92
An interconnection is provided between output parameter RdDataOut of the block MMOrptn
and input parameter
RdData of the block MMDiag to enable the acyclic reading of DS92.
Data record 92 is read acyclically, i.e. it is only read when a
ReadData operation is triggered
at MMOprtn or when either a trip or a warning is triggered by the device.
4.2.3
Message characteristics
MMDiag signals the following errors/faults:
● DP/IO station fault (
Rack1Err, Rack2Err)
● Rack fault (
RackF_Act)
● Module fault (
ModF_Act)
● Connection fault (
BusFlt)
An error generates a group error
GrpErr in output parameter Err_Act.
The
Subn1_Id and Subn2_Id parameters of the SUBNET function block (FB106) are linked
with the
Subn1Id and Subn2Id parameters of the MMDiag block. These parameters forward
the error information of the primary and redundant master system. This information is
provided to output parameters
Rack1Err and Rack2Err of the MMDiag block.
