High speed counters ML1100

[GL3NN 3]

Hi Gurus i understand the ML 1100  has 1 20Khz high-speed counter. The counter has four dedicated inputs ive got inputs I:0/0 and I:0/1 connected to an encoder and it counts away dream and i can see it displayed on HSC.0.ACC but how can i get Inputs I:0/3 and I:0/4 working for a second encoder? iv connected the second encoder and can see the inputs blinking on the ML 1100 so i think its an addressing issue how do i read those pulses ive made sure the filter in the I/O config is set low enough to read the pulses and set Mode to 7 in the function files

 

as always your help is much appreciated

There is only one HSC on the ML 1100. ML 1500 has two.
The above thread points this out.
