Thank you Ray and Aramane *SP for giving out the correct code... Good news... This could compile and load the EPL. What I did is...#define FASTSCAN 0definemodule(1,FASTSCAN,0,1):INIT{senddata(1,0,0b00000000);senddata(1,1,0b00000000);senddata(1,2,0b00000000);senddata(1,3,0b00000000);};Unfortunately I dont see any button from 48-56 showing out in red/green which shown output/input data has send/received. Apparently from what I think, EPIC cannot read the rotary encoder I am using which is PANASONIC EVQ-VEM (2 Phase mechanical) I think I filled out the incorrect code ('senddata(1,0,0b00000000))' do you have any idea what those code are? Is there a way I could understand senddata binary stuffs, where do I find those information. On EPIC manual it did not explain those clear enough. Let me know if anyone can help me out.

This code says to epic rotary module what kind of encoders you use.Senddata(7,0,0b01010101) in this line you have 4"01"so 4 2 phase optical in module 7 row 0Sendata(7,1,0b11111111) in this line you have 4(11)so 4 type 3 encoderssenddata(7,0,0b11111111);This is my code usingsenddata(7,1,0b11111111);20 type 3 grayhill encoders.senddata(7,2,0b11111111);senddata(7,3,0b11111111);senddata(7,4,0b11111111);Look again to Rays'message.00 //default01 //2phase optical10 //Alps11 //type 3 grayhill c62I will send you more information by Email.

I am using 2 Phase Mechanical not optical.... would that make any difference??

Be sure you are defning module 7 as the Rotary encoder module. Your last example shows Module 1.This may also be an issue where you need to re-generate a new BUTTONS.CFG file, but let's see what happens when you DEFINEMODULE as #7 first.

I just thought if I use 12 rotary encoders on module 1, from row 1 to 3 would be best in use and have all of the button on Module 1 from 4-??. FYI: I have not created button/swich on EPL as of yet. would it be a bad idea?? Let me know
