S7-300 Module 6ES7 331-7HF01-0AB0 – New Product Release 03
The product release of the analog input module with order no. 6ES7 331-7HF01-0AB0 has been incremented to E03.
Reason for the change:
In very isolated cases the position of the measuring range cube of the analog input module with order no. 6ES7 331-7HF01-0AB0 and product releases ES01 and ES02 is not detected correctly. As a result, the module will supply incorrect measured values. The problem shows itself immediately after the supply voltage (L+) is switched on and can therefore be discovered during commissioning. If the position of the measuring range cube is not changed during operation, the probability of a subsequent failure is very small. The problem has been corrected with product release ES03.
If one of your modules is affected by the problem, please speak to your SIMATIC contact at your local Siemens office about upgrading.
