Hi, Does anyone have / know where I can find an official 'changelog' of firmware versions for input and output units? In particular I am after Classic Series Input Units, but would be nice to have for all units. Stock rotation at both Schneider and many of the local electrical wholesalers over here is very poor - the new gear obviously gets put at the front of the shelves - and consequently we **often** get very old gear turn up at a job. I've recently got approx 20 units of C2000 Series 1 and 2 button switches for a job - of these more than half of them were more than 3 years old according to the date on the box. Some were 6 or 7 years old. This is one of the worse cases I've seen. Consequently, I have some units which are version 1.2.67, others that are 2.2.00 and others that are 2.4.00. This is all a bit frustrating as one of my colleagues installed the switches and it was not until I was onsite programming that I noticed how old some of them were. Half of me says to take them back, the other half of me says forget it as it will take time (and therefore money) to change out the units! Can anyone tell me what changed between these versions of classic KEY1 KEY2 and KEY4 units? 2.4.00 2.2.00 1.2.67 If these versions include bug fixes I'll be having some strong words with our wholesaler. If it is only learn mode features etc. I'm not going to be so worried, still a pain in the ass though - when a product is not field upgradeable one would expect to receive new firmware when buying new gear! Cheers, Jonathan.
