Hello
Could someone tell me if you can use more than 1 shift register with a Mitsubishi FX1s plc and GX developer.
The following is what I’m trying to accomplish.
I have a long conveyor with fixed chain pin spaces. There are multiple inserting stations upstream (there can be up to 32 stations in use at one time). These inserting stations feed different products onto the conveyor. I need to track each station down the line and fire an output for certain feeds. Example: if station 1 feeds, then I need to fire an output at a certain distance down the line, if station 2 feeds I don’t need to fire the output , if 3 and 4 feed I need the output to fire…
I can track one station with a shift register, but when I try to set up another register it counts down by 2. I have the manual and have read up on this but it doesn’t say anything about multiple shift registers
Is there a different way of going about this?
I am not a programmer by trade, just a Technician, so excuse my lack of knowledge in this area.
Any help would be appreciated
