Explanation
Terminating an existing permanent connection
The input serves to trigger termination of an existing permanent connection to
the subscriber specified with "PartnerNo".
A permanent connection to the subscriber is terminated with a 1 signal at this
input if there is currently a permanent connection to this subscriber. The input
is then automatically reset by the FC. If an input of a digital input is specified (I
0.0 ... I n.7), you are responsible for resetting the signal at the input via the
user program. This should be done at the latest before establishing a perma-
nent connection again.
Depending on whether the subscriber can be reached over a dial-up connec-
tion or a dedicated line, the command to terminate the permanent connection
is processed as follows and indicated at the "PartnerStatus" output:
•
For a dial-up connection:
The existing dial-up connection is terminated by the master TIM but only
after any pending data has been sent.
The current status of the permanent connection is indicated in the
PartnerStatus output word with the bits 4 ... 6 (see PartnerStatus
parameter).
•
For a dedicated line:
The master TIM deletes the registration for continuous polling of the
corresponding subscriber. The polling cycle for all connected subscribers
continues in normal mode.
The current status of the continuous polling is indicated by bit 8 in the
"PartnerStatus" output parameter.
Continuous polling can also be canceled on a dedicated line by instructing
the master TIM to start continuous polling of another subscriber. The
existing job is then replaced by the new one.
Special feature with stations:
A permanent connection cannot be terminated by a station. This control input
cannot therefore be used when FC PartnerMonitor is used in a station.

FC PartnerStatus
Function
The FC PartnerStatus can show the current status ’disrupted’ or ’OK’ for a maximum of 8
SINAUT subscribers.
The FC can be called at any point in the cyclic user program (in OB1).
If you want to monitor more than 8 subscribers, include the appropriate number of FCs
PartnerStatus in the user program.
The partner can be an ST7 CPU or an ST7cc to which a connection was configured, or a
local TIM.
