I am working on something different. I have a Signal Speaker that uses binary inputs to play a certain song based on source configuration. I have to send 24v to the inputs of the speaker. I have 5 of them with 30 different configurations. I am currently trying to do this in ladder logic, RSLogix 5000. Steps done. 1. Assigned the 6 outputs tag names. This is so that I can shift the program to other machines if I have to and I just need to change the slot location, or if I have an output go bad I can move it with ease. This works. 2. I created the 30 lines of 5 columns to match the binary method. This works. a. I can manually toggle the output to cycle thru the binary table. 3. Currently working on the logic that when a particular alarm is activated... I turn on the outputs needed to match the binary table. The problem is destructive bit reference on the coils. I was researching some but don't know what direction to go. How can I call the same output on different rungs? I have attached the .L5X to show what I have programmed. 4. I know the first rungs are wrong. That is what I am trying to fix. 5. Would there be a better way to address this, if so how? Any help would be greatly appreciated.

horvatmiha posted a topic in SiemensHello! I am using S7-1200 PLC 1212C AC/DC with configured Modbus TCP Server. I can already read/write Inputs/Outputs (Coils) and Memory Words. However I'd like to read/write Memory BITS. Is it possible? If so, how? What addresses should I use in TIA portal? And which function codes on client side? Thanks in advance!
