STF utility with
SIMADYN D as
client
3-40
• p
Number of the CPU on which the SIMADYN D utility is configured.
Possible values: 1...8
• d
Identification code for a SIMADYN D utility. This utility sets-up an
object.
Possible values:
− P: For process data
− M: For the message system
Using the STF utility "Interrogate name list", a client which has been
removed can interrogate a list of the configured SIMADYN D utilities. The
client receives information about the structure of the objects and how
these objects are to be handled.
Process data is transferred via SINEC H1 layer 7 (STF) by reading and
writing data. SIMADYN D can be both a server as well as a client (CFC
configuring). Process data have an open structure as far as SINEC H1 is
concerned.
• The channel name is specified at connection AR of the receive block.
A remote client can execute the STF utility "Write" on this variable.
• The channel name is specified at connection AT of the transmit block.
A remote client can execute the STF utility "Read" on this variable.
• The SIMADYN D utility ID at the end of the variable name is "P".
Address examples:
1. Subrack "BGT1", CPU No. 3, function block CRV is to be configured:
− AR- 'PZDWRITE'
− thus, the following variable name is obtained:
PZDWRITEBGT1__3P
− the variable can be written into.
2. Subrack "BGT3", CPU No. 7, function block CTV is to be configured:
− AT- 'PZDREAD'
− thus the following variable name is obtained:
PZDREAD_BGT3__7P
− the variable can be read.
• The channel name, address stage 1 and address stage 2 are
specified at connection AT of the transmit block. SIMADYN D
executes the STF utility "Write" on the remote variable.
