VT1422A Command Reference 255 Chapter 7
ALGorithm
Notes
1. When the number of update requests exceeds the Update Queue size set with
ALG:UPD:WINDOW by one, the module will refuse the request and will
issue the error message "Too many updates in queue. Must send UPDATE
command." Send ALG:UPDATE, then re-send the update request that caused
the error.
2. The "Too many updates in queue..." error can occur before the module is
INITialized. It's not uncommon with several algorithms defined to have more
variables that need to be pre-set before INIT than will be changed in one
update after the algorithms are running. It may be necessary to send INIT with
updates pending. The INIT command automatically performs the updates
before starting the algorithms.
ALGOrithm:UPDate:WINDow?
ALGOrithm:UPDate:WINDow? returns the number of variable and algorithm
updates allowed within the UPDATE window.
