The warning triangle in the column of the dynamic station resources is displayed because
the sum of the maximum available connection resources of CPU, CP and CM
(= 310 connection resources) exceeds the station limit of 256.
Note
Available connection resources exceeded
STEP
7 signals the exceeding of the station-specific connection resources with a warning.
To make full use of the connection resources from the CPU, CP and CM, either use a CPU
with a higher maximum number of available st
ation-specific connection resources or reduce
the number of communications connections.
② Module-specific connection resources
The columns of the module-specific connection resources provide information about the use
of resources on the CPUs, CPs and CMs of an automation system:
The display is per module and not per interface.
In the example, the CPU makes a maximum of 128 connection resources available, of which
18 are already in use and 110 still available.
The used resources are divided up as follows:
● 6 resources for HMI communication
● 4 resources for S7 communication
● 8 resources for Open User Communication
