Timing Charts by Assembly Type
Read is executed by the Read (TRIG) Signal.
The timing signal at completion of storing the Read data to PLC data memory
differs by the Input
Assembly type.

(1) Reading starts at the rising edge of the Trigger.
(2) At start of Read, InReadCycle turns ON and Trigger turns OFF.
(3) At end of Read, the Read data is stored in Decode Data and InReadCycle turns OFF.
