hi all bit of info needed,I want to wire up an encoder i have to a fx plc. i believe/ would like to use hs counter c252 where x0 is A encoder output,x1 is B & x2 rest. the encoder i have came with following details: Features: 400 p / r (Single-phase 400 pulses / R, Two phase 4 frequency doubling to 1600 pulses) Power source: DC5-24V Shaft: 6 * 13mm / 0.23 * 0.51 ″ Size: 38 * 35.5mm / 1.49 * 1.39 ″ Output: AB 2phase output rectangular orthogonal pulse circuit, the output for the NPN open collector output type Maximum mechanical speed: 5000 R / min Response frequency: 0-20KHz Cable length: 1.5 meters Notice: AB 2phase output must not be directly connected with VCC, otherwise, will burn the output triode because of different batches, and may not have the terminal Package included: 1 X Incremental Rotary Encoder Connection: Green = A phase, white = B phase, red = Vcc power supply, black = V0 I gather from this that I connect green - x0,white-x1, red to 24v & black/shield to 0v & rest button x2 I also believe as it is npn output  would I connect 0v to the s/s terminal.(sink?) what i need to know is if i connect 24v to the s/s terminal would this damage the encoder & if all my above assumptions are correct.

hi all never mind I got it all sorted now it only works in a fashion with gx developer

hi saw one of these on eBay.co.uk  thought I would give it a try PLC FX1N-20MR & Rail Type Housing & PLC Display Relay Module Delay Module 10-28V item 113675779023 but unable to get display to respond was wondering if anyone has any ideas or any experience with them I am using gx- developer fx 8.45 and can communicate to it

the markings of wires leads me to belive its a two channle encoder vcc 0v A B SHIELD MARKED F.G.

hi it is a fx -48mr

Hi all purchased a couple of encoders from china to get into swing of using the fx plc From my investigations i found the encoders are incremential type .they have g40b-6-400-2-24 marked on them so i believe the g40b refers to the encoders diameter as it is 40mm ,the 6 to the shaft dia as it is 6mm, 400 i think is pprev the 2 for 2 channle & 24 indicating 24 volt dc there are 5 wires which i have managed to identify as red = vcc black = 0v yellow = a green = b & there is a bare copper wire which is the shield. so far so good i thought it would be just a matter of connecting it up to the fx & turning the shaft & monitoring on gx developer. so i decided to use hsc 255 & connect red black to 24v supply on plc A channle to input x3 B channle to input x4 connecting a switch to x5 rest & x7 start did a bit of code using a n/o m8000 to drive hsc c255 with k 999 thinking that when online by turning shaft & turning on x7 i would see value of c255 alter accordingly wrong had to be as it was to simple so could someone please point me to my error?

many thanks for that, sorted.

hi i am having a bit of a problem ,i have eight proxies that should make once for every revolution of a shaft so i want to workout the number of revolution so tried to use the following: div c200 k8 d8 where c200 is count from a bi directional counter but this do not seem to work. any idea's anyone? cheers terry

thanks for that, i thought so

hi all i am right in thinking that the fastest pulse count that can be read on a ib32 input card is determined by the scan time,as i have a device connected to a input which runs at 110 hz but believe this is to fast for plc to cont correctly unless i resort to using the a hsc card.
