Communication specifications
Communication specifications of CC-Link IE TSN
*1 The communication cycle depends on the controller specifications and the number of the connected axes.
*2 There are restrictions on the communication cycle depending on the function used. For details, refer to "Function restrictions" in the
following manual.
MR-JET-G User's Manual (Introduction)
*3 The communication speed can be set to 1 Gbps or 100 Mbps. 100 Mbps can be used with servo amplifiers with firmware version B6 or
later. When 100 Mbps is selected, the minimum communication cycle is 500 μs. When using 100 Mbps, set [Pr. NPA12 Communication
speed] to "1h". For details, refer to "Network basic parameters" in the following manual.
MR-JET-G User's Manual (Parameters)
*4 The cycle of the cyclic transmission must match the communication cycle. When using GX Works3, select "Communication Period
Setting" in "Module parameter (network)", then modify "Basic Period Setting".

Cyclic transmission [Motion mode]
Communicates data cyclically between stations using PDOs.
• Maximum RPDO size: 80 bytes/axis
• Maximum TPDO size: 80 bytes/axis
• The servo amplifiers support variable PDO mapping.

Transient transmission [Motion mode]
Communicates data non-cyclically between stations using
SLMP and other protocols. SDOs can be used to read and
write objects of the servo amplifier.
