Configuration and operation
5.11 STEP 7 configuration of individual parameters
CP 1243-1 PCC
46 Operating Instructions, 02/2015, C79000-G8976-C384-01
●
Description of the operation center e.g. name of the server.
●
Monitoring time for operation center
If the CP does not receive a response from the communications partner (operation
center) within the configured time, the CP interprets this as a fault/error on the partner.
With 0, after 5 minutes the lack of a response is interpreted as a connection problem.
●
Connection monitoring time
If the establishment of an HTTPS connection to the communications partner (operation
center) fails, this is interpreted as a connection problem.
●
Value for the wait time until the next connection establishment following an unsuccessful
attempt to establish a connection.
The reconnection delay is the waiting time between repeated attempts to establish the
connection by the CP when the operation center is not reachable or the connection has
aborted.
A value is configured for the waiting time before the next connection establishment
attempt.
With the value 0, the attempts until successful connection establishment are made as
default at the following intervals: 3 x 60 s, 3 x 120 s, 4 x 900 s, 23 x 3 600 s (1 hour),
1 x 86 400 s (1 day).
●
Report operation center status
If the "Report operation center status" function is enabled, the CP signals the status of the
communication to the operation center.
– Bit 0 of "PLC tag for operation center status" (data type WORD) is set to 1 if the
operation center can be reached.
– Bit 1 is set to 1 if all the paths to the operation center are OK (useful with redundant
paths).
– Bits 2-3 indicate the status of the send buffer (frame memory).
The following values are possible:
- 0: send buffer OK
- 1: send buffer threatening to overflow (more than 80 % full).
- 3: send buffer has overflowed (fill level 100 % reached).
As soon as the fill level drops below 50%, bits 2 and 3 are reset to 0.
Bits 4 to 15 of the PLC tags are not used and do not need to be evaluated in the program.
