System- and communication configuring D7-SYS - SIMADYN D
Edition 12.2003
•
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
NOTE
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.
3.4.4.2 Communications
utility, process data
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.
