UR20-8AI-I-PLC-INT (1315670000)
Version 01.02.01 Release date: June, 2020
• Bug fix for 8 channel HD modules: Correct behaviour of diagnosis and status LED for undervoltage detection
• Bug fix for 4 channel modules: Improved shortcut behaviour
Version 01.02.00 Release date: August, 2019
• Bug fix: Fixed that module sometimes remains in fault state when (re-)booted at high temperature.
Version 01.01.00 Release date: July, 2019
• Changed the value range for the FORCE mode of the webserver, now low-level values for the range of
underloading can be set
• Fixed that the channel error LED stays off when lower or upper limits are exceeded
• Reduced the crosstalk between the input channels
• Removed toggling diagnosis between “Overload” and “Upper limit value exceeded”, when an input channel
is overloaded
• Adjusted behaviour of module diagnostics:
- Module diagnostics are always active (in case of an error the module status LED will be red)
- In case of an error the channel error LED will always be red on modules which are supporting
single channel diagnostic, independent of the configuration for the diagnostic
