WatchDog
The "WatchDog" system object can be included as an option. It indicates to the CPU
program whether the communication between CPU and local TIM is still working; in other
words, whether TD7onTIM is still reading from and writing to the memory areas of the CPU.
As long as communication is functioning correctly, a selectable output bit changes state at 5
second intervals. The constant status change can be evaluated by the CPU user program.
Parameters in the "Output Bit" box:
Name:
Output bit
Memory area:
The following options are available:
•
DB: Data block
•
Memory bit: Memory bit area
•
Output: Process output image (PIQ)
DB No.:
Specifies the DB number in the CPU if the data block memory area (DB) was
selected
Address
[Byte.Bit]:
Input fields for the byte and bit number in the selected memory area
PartnerStatus
The optional PartnerStatus object can be used to monitor the reachability of up to 8
communications partners (DNP3 master stations). The status is made available to the CPU
in an output byte. One bit per communications partner is reserved in the output byte to
indicate the status of the partner:
If TD7onTIM has a connection to more than 8 partners whose status needs to be monitored,
the "PartnerStatus" system object needs to be configured more than once.
