Example of program
Example of wiring
1) In the case of sink wiring
Use the sink only input, sink only output type main unit, a sink only input type input extension block and a
transistor output (sink only output) type output extension block. The wiring example is the [FX
3UC-32MT/
D or FX
3UC-32MT-LT] + input extension block [FX2NC-16EX] + output extension block [FX2NC-16EYT].
2) In the case of source wiring
Use the sink/source common input, source only output type main unit, a sink/source common input type
input extension block and a transistor output (source only output) type output extension block. The wiring
example is the [FX
3UC-32MT/DSS] + input extension block [FX2NC-16EX-DS] + output extension block
[FX2NC-16EYT-DSS].
