Streaming interval and improved performance from SNAP-PAC-R controllers


Applies To:

SNAP-PAC-R1 Controller Firmware
SNAP-PAC-R2 Controller Firmware

Versions Affected:

Problem was introduced in version: R7.1a
Problem is resolved in version: R7.1e

Resolved In Version:

Problem is resolved in version: R7.1e


Symptoms:

ioControl strategy logic performance is doubled if the stream interval is changed from 0 ms to 1000 ms.


Workaround:

Use ioManager to change the streaming interval. From ioManager, select Tools→Inspect, Communications→Streaming. Change the value from 0 to 1000 for Stream Interval (milliseconds).


Resolution:

Opto 22 has resolved this issue. Note, if the I/O unit configuration was stored to flash when the control engine had firmware version R7.1D or earlier, the streaming interval must be manually changed. Resave the I/O unit configuration to flash to retain this updated configuration.
