# Summary

_A pose received from primary interface has different type byte than the one described in [Client\_Interface\_V3.13andV5.8.xlsx](https://s3-eu-west-1.amazonaws.com/ur-support-site/16496/Client_Interface_V3.13andV5.8.xlsx): 12 (0c in hex) instead of 10 (0a in hex)_

# Versions

- Affected Robot Software Version(s): URSim 5.9.1

# Impact

_I am not sure to read correctly the variables from Primary Interface._

# Issue details

_Probably the `.xlsx` file is not updated to the latest software version (5.9.1) where matrix variable was introduced._

## Use Case and Setup

_I want to see the actual value of URScript variables in URCaps._

## Steps to Reproduce

_Read primary interface messages._

## Expected Behavior

_I receive a BOOL\_VAL variable when the type byte is 12._

## Actual Behavior

_I receive a POSE\_VAL variable when the type byte is 12._

## Workaround Suggestion

_Update the Client Interface documentation or check the byte sent by the Primary Interface_
