2. System Function The extension module connected to the right side of DVP10MC11T DVP10MC11T can also connect all Slim series of extension modules with the digital quantity of max. 240 input points and 240 output points in its right side. Besides, max. 8 special modules with non-digital quantity such as analog-quantity module, temperature module, pulse module and etc. can be connected to the right side of DVP10MC11T. The number of digital input/ output point is reflected with X and Y and the functions are as follows. The number of input/ output point: (Octal) X20 ~ X27......, X70 ~ X77, X100 ~ X107... Y20 ~ Y27......, Y70 ~ Y77, Y100 ~ Y107... Note:
The number of digital points of the digital-quantity extension module on the right of DVP10MC11T starts from 20. Suppose that the input point for the first digital-quantity extension module starts from X20 and output point starts from Y20. The numbers of input point and output point are added by 8’s multiple; it is counted as 8 points if the number is less than 8. The number of special modules The extension modules on the right side of DVP10MC11T like analog-quantity module, temperature module and pulse module are called special modules. The number of the first special module on the right side of 10MC is 0; the number of the second one is 1, and so on.
PLC module could access the special module according to such serial numbers through executing FROM/TO instruction. AIAO and DIDO …… DVP-MC operating manual 2-7
