10 Programming
Restrictions at mixed
operation
402
Mixed operation means that the following devices are connected to the
JX2 system bus:
JX2-I/O modules

JX2 slave modules

 CANopen® devices which are not supported by the JX2 system bus driver
and which must be programmed via CANopen® STX API
In this case, the following restrictions apply:
 Only the ranges 50 ... 59 and 70 ... 79 are permitted to be node IDs for the
CANopen® devices!
If the node ID range 50 ... 59 must be applied, only nine JX2-I/O modules

at the most can still be connected to the JX2 system bus. Otherwise, the
CAN IDs used will overlap with the PDO IDs.
Important note: There is no scanning by the controller.
 To be able to connect more than nine JX2-I/O modules, the COB IDs of
TX and RX PDOs used by CANopen® devices must be mapped to the ID
range 70 ... 79.
Important note: Whether it is possible to make changes to the COB ID of
PDOs depends on the corresponding CANopen® device.
 The non-volatile register 200002077 lets you disable the CANopen®
support on part of the JX system bus driver. For more information refer to
the sample codes below:
// JX2 system bus driver not supporting CANopen®
// and CAN-Prim disabled
Regs[200002077] := 0x40;
// JX2 system bus driver not supporting CANopen®
// and CAN-Prim enabled
Regs[200002077] := 0x44;
If you intend to program communication with CANopen® devices via
CANopen® STX API yourself, only WAGO I/O System 750, JX-SIO, LioN-S
modules, etc. can be connected to the JX2 system bus.
To have the changes accepted, relaunch the controller once.
