I/O Point Mismatch Errors Generated by Some Discrete Channels on RIO

Applies To:

Firmware for GRV-EPIC-PR1

Versions Affected:

2.0.1

Resolved In Version:

2.0.2

Symptoms:

In PAC Control, if you configure a channel on a GRV-R7-MM1001-10 with any of the following signal types and features, PAC Control may show one or more "I/O point mismatch" errors in the error queue and the I/O configuration may not match the configuration specified in the strategy:

Signal Type	Features
DI: 5-30 VDC	Counter, On-Pulse, Off-Pulse, Frequency, Period, On-Time Totalizer, Off-Time Totalizer
DI: Switch Input, Powered	Counter, On-Pulse, Off-Pulse, Frequency, Period, On-Time Totalizer, Off-Time Totalizer
DO: 5-30 VDC	TPO

When you download and run the strategy, PAC Control places an "I/O point mismatch" error in the error queue for each channel whose configuration in the strategy meets the above criteria. The resulting channel configuration may change as follows:

Starting Configuration	Specified in the Strategy	Resulting Configuration (as shown in groov Manage)
DI: 5 - 30 VDC DI: Switch Input, Powered	DI: 5 - 30 VDC with any of the indicated features	DI: 5 - 30 VDC with a feature
DI: 5 - 30 VDC	DI: Switch Input, Powered DO: 5-30 VDC with feature	DI: 5 - 30 VDC with no feature and "I/O point mismatch" error
DI: Switch Input, Powered	DI: Switch Input, Powered DO: 5 - 30 VDC with feature	DI: 5 - 30 VDC with no feature and "I/O point mismatch" error
DO: 5 - 30 VDC	DI: 5 - 30 VDC DI: Switch Input, Powered with feature	DI: 5 - 30 VDC with feature and "I/O point mismatch" error
DO: 5 - 30 VDC	DO 5 - 30 VDC with feature	DI: 5 - 30 VDC with no feature and "I/O point mismatch" error
