I/O Map
Because we added an Additional I/O Power Supply Unit, add 1 to the corresponding numbers that
represent the position and variable of the NX-ID3344 and NX-OD2154 in the example for an Ether-
CAT Slave Terminal, as shown below.
Posi-
tion
Unit2 Input Bit 00 Time Stamp
Unit3 Output Bit 00 Time Stamp
Unit3 Output Bit 00
Unit3 Output Bit 00 Output Status
When Units are connected to the CPU Unit, the Time Stamp of Synchronous Output uses the follow-
ing data. It is I/O data for the NX Bus Function Module, which is allocated to the CPU Unit for each
NX Unit.

tion
NXBus- N3 Time Stamp
Master of Synchro-
nous Output
Use the above variable for the sample programming in the example for an EtherCAT Slave Terminal.
Task Period of the Primary Periodic Task
The minimum value for the task period of the primary periodic task in the NX1P2 CPU Unit is 2ms.
1ms in the EtherCAT Slave Terminal example cannot be set.
