CIMPLICITYHMI IPC Counters
The System Sentry provides CIMPLICITY counters for the Inter-process Communications sub-system.
Accumulated totals since the project started
| For | Other Counter | Indicates if the Device is Currently: |
|---|---|---|
| A | Messages Sent | Messages sent by one or all processes. A number higher or lower than expectation may indicate a problem |
| A | Messages Received | Messages received by one or all processes. A number lower than messages sent indicates that one or more processes is not processing the messages as quickly as it is receiving them. The acceptable difference depends on the system and which process is being monitored. |
| A | Logical Link Writes | Writes performed over the logical links. A logical link is a direct connection between processes, as opposed to sending the data through a router. |
| A | Logical Link Reads | Reads performed over the logical links. |
| N | Write Retries | Times a write operation was retried. If a process tries to write to a port and fails, it tries again. Write Retries can indicate that a process is backing up. Important: Retries will not occur on unsolicited communication; unsolicited communication requires two transmission failures before a retry occurs. |
Indicators of current performance

|---|---|---|
| E | Ports | Software ports created by one or all projects' processes. A process might create entry ports at startup or continuously while it is running. |

| A | Messages Received/sec | Messages being received by one or all processes per second. |
