If the external input/output signal allocation or concurrent ladderprogram is changed, the allocation will be changed according to thecontent changed.Note 2) Regarding the detail of input data/output data on JANCD-YIO21-E(Standard I/O Board), refer to DX200 Instructions.Note 3) Regarding JANCD-YIO21-E (standard I/O board), YSF21 (YIO21base board) is displayed on IO Module Setup display.I/O Allocation Examples (For Handling)NOTEWhen the PROFINET communication is disconnected, thetransmission data allocated for the concurrent I/O keeps theprevious value. (The value is not cleared to 0.) Also, whenthe CP1616 is used as an IO controller, the previous valueis also kept when the IOPS status of the communicationdestination (IO device) has an error.However, when turning ON the DX200, the previous valueis cleared to 0, not kept.20010 - 25127(4096 points)30010 - 35127(4096 points)PROFINETCommunicationPROFINETCommunicationand forwardingto DX200Concurrent IOCP1616PROFINET Device• JANCD-YIO21-E (Standard I/O)IO size: 5 Byte (fixed)• CP1616 (PROFINET)(1) IO controller: Enabled(2) IO size (IN/OUT): 16 Byte73 of 103
