9.3.1 Client Command Errors
Each SIE Client has an associated status data area located in the
gateway’s
upper memory. The Data Map functionality of the gateway can be used to map
this data into the normal user data range of the gateway
(page 27).
The following table lists the starting addresses in upper memory where the status
data for each Client can be found.

Command List Errors (16 per Client)
For every command that has an error, the gateway automatically sets the poll
delay parameter to 30 seconds. This instructs the gateway to wait 30 seconds
before it attempts to issue the command again.
