*1. If only a definition is given in the above table, refer to the data of the NX Units in Section 1 Data List or the
manuals for the specific NX Units for the values of the items.
Remarks
Type Model
Digital Output Units Models support synchro-
nous I/O refreshing
0 [μs] −
Digital Mixed I/O Units 0 [μs] The value for digital outputs.
Analog Output Units Conversion time
× Number of
points
The conversion time and number of
points depend on the model of the
Unit.
Incremental Encoder
Input Units
40 [μs] This is the value for command val-
ues and other output data process-
ing.
*2
*2. Incremental Encoder Input Units and SSI Input Units perform processing for command values and other
output data. Therefore, if there are any of these Units that operate with synchronous I/O refreshing in the
configuration, they must be included in the Tmax-OutProc calculations.
SSI Input Units 40 [μs]
Pulse Output Units NX-PG0122
/-PG0112
70 [μs] The value for pulse outputs and
external outputs.
NX-PG0232-5
/-PG0242-5
95 [μs]
NX-PG0332-5
/-PG0342-5
160 [μs]
Load Cell Input Unit NX-RS1201 35 [µs] This is the value for operation com-
mands and other output data pro-
cessing.
*3
*3. The Load Cell Input Unit performs processing for operation commands and other output data. Therefore, if
there is a Load Cell Input Unit that operates with synchronous I/O refreshing in the configuration, the Unit
must be included in the Tmax-OutProc calculations.

ON/OFF
response time +
Input filter time
The ON/OFF response time
depends on the model of the Unit.
You can set the input filter time for
each Unit.
Digital Mixed I/O Units ON/OFF
response time +
Input filter time
This is applicable to the digital
inputs.
The ON/OFF response time
depends on the model of the Unit.
You can set the input filter time for
each Unit.
Analog Input Units Conversion time
× Number of
points
The conversion time and number of
points depend on the model of the
Unit.
Incremental Encoder
Input Units
0 [μs] The value for pulse inputs and exter-
nal inputs.
SSI Input Units 0 [μs] −
