With redundancy (ET 200 SP HA), connection takes place with the two quality bits:
● The input parameter
ProImQB
is interconnected with the icon of the quality bit of the master
channel.
● The input parameter
ProImQBSlv
is interconnected with the icon of the quality bit of the
slave channel.
Write the first slot's address that was generated in HW Config to input parameter
Laddr
.
Note
If you are not using the CFC function "Generate module drivers", parameterize the addresses
of input structure Addr and the Mode in/out parameter manually. The block expects the values
Mode = 16#80xxxxxx for "I/O data can be read", and 16#00xxxxxx for "Invalid I/O data".
A template for process tag types is available in the SITRANS Library as an example for the
PiDr64/256 block:

Startup characteristics
The PiDr64/256 block resets the totalizer for the diagnostics data
(output
AcyclData.NewDiag
) to zero and sets an internal bit memory to zero to read the
current diagnostics data in the cyclic call.
Status word allocation for
Status
parameter
This block does not have the
Status
parameter.
18.1.2
Operating modes of PiDr64/256
This block does not have any operating modes.
18.1.3
Functions of PiDr64/256
The functions for this block are listed below.
Reading acyclic values from the DP slave
Reading of acyclic data is initiated by writing the number of the data record to be read to
output
AcyclData.ReqRd
. The number of the slot from which the data is read must be set
simultaneously at output
AcyclData.SlotRd
, while the data record length in bytes is set at
output
AcyclData.LenRd
.
On completion of the read cycle (with/without error), the block copies the number of the data
record that was read to output AcyclData.RdyRead. The read data is now available in output
Driver blocks
