EGD Commands may return COMMREQ Status 9590H (= internal error) instead
of the expected B190H (= Can’t locate remote node) when unable to locate a
remote device on the network.
Very heavy EGD
production/consumption at server
may cause EGD command timeouts
Very heavy EGD production and/or consumption at a server device may cause
EGD command timeout errors when another device attempts to send EGD
commands to that server. If EGD commands must preempt normal production,
you may set the “gcmd_pri” Advanced User Parameter to 2 (see GFK-2224,
Appendix A). Note that by doing so, EGD exchange production may be delayed.
SRTP server errors can cause
timeouts at channels client
The SRTP Server in the PACSystems Ethernet Interface can encounter various
errors when the remote Series 90 client takes down an SRTP connection and then
establishes a new connection. This can cause unexpected channel timeout errors
0190H or 0290H at the client.
The SRTP server errors in the Ethernet exception log are identified as Event = 2;
Entry 2 may be 001cH, or 0021H. When an EGD Command attempts a write operation to a bit-mode reference
memory range (%I, %Q; %T, %M, %SA, %SB, %SC) where the amount of data
be written exceeds the configured size of that reference memory, the command
will return failure status but partial data may be written into the reference memory.
The amount of partial data written depends upon the starting bit memory location
and the data length as follows:
? If data starts on a byte boundary (location = (8*n) + 1), no partial data is
written.
? If data does not start on a byte boundary (location = (8*n)+1) and data
exceeds the configured reference memory by 8 or more bits, partial data is
written from the starting location to the next byte boundary after the starting
location.
? If data does not start on a byte boundary (location = (8*n)+1) and data
exceeds the configured reference memory by less than 8 bits, partial data is
written from the stating location to the end of configured reference memory.
For a Write PLC Memory command, this can occur when writing data into the
target PLC. For Read PLC Memory or Read Exchange commands, this can occur
when writing data received from the target controller into the local memory. The
logic application must not use any data returned to the local controller if the EGD
command status indicates failure.
To avoid writing partial data to the local or remote controller, be sure that bit
memory data transfers do not exceed the configured reference memory sizes at
the appropriate controller.
