Meter and Position Transmitter Interfaces

The group of meter and position transmitter interfaces is divided into
5 types of modules:
Type of module
The provider and consumer status (IOPS) of the input or output information
are exchanged between the I/O controller and I/O device in both directions
with meter and position transmitter interfaces. With the SSI Interface 75x-630,
there is also an additional possibility for exclusively transmitting the input
data of the transmitter. In this case, the I/O device only receives the consumer
status (IOCS) from the I/O controller and supplies it with the provider status
(IOPS).
The following table shows a list of the number of bytes for the individual
modules that are allocated in the respective process image (PA) and the
telegrams (TLG) in the direction of transmission and reception (Tx, Rx).
