I've got a 300 with Motionview that I'm going to run using the IOD connector with discrete signals. First time to touch one of these. I see the pin 29 is enable/inhibit. I've tried +24VDC, 0v, and nothing and the drive will never 'enable'. What am I missing? I've got the the STO where the safety1 & 2 inputs are tied to +24VDC and the commons shorted together. I tried unshorting the commons. I tried removing the connector altogether. I've read the manual, there nothing mentioning 'enabling' other than that pin 29 being high, which obviously doesn't work for me. Any help?
Good morning all! I'm just getting into this world of controls and automation and need a way to simplify my life when it comes to discrete alarms. I do not care to separate them by tag so long as I can create a personalized for each bit/alarm triggered. What is the best way to list hundreds of alarms in a single tag? Can we make use of a struct data type? If so, what would this look like? I understand I can use something like a tag of data type word, such as "Faults" MW100 and then reference M101.0, M101.1... M100.0, M100.1 (notice the order), but this only allows me 16 total discretes per tag. Sometimes I'll have more alarms than 16 and sometimes way less. I'd rather not seperate them in this manner if I can avoid it. Your assistance is much appreciated!  Siemens TIA and WinCC v15
