Table 4-3:

Special

Data Addressing

*1: The Max. AI/AO address is decided by the maximum AI/AO channels
configuration by utility. For e

xample, if users finish the configuration by the

GW-7433D utility, check the mapping table and find that there are 8 AI data
(16-bytes) assigned in the Modbus memory, the Max. AI address is 0007h (or
30008h for PLC) because the useful AI channel is from 0 ~ 7.

*2:

“n” is the CANopen slave device number. The number range is 1 ~ 10.

*3:

“N” is the total CANopen slave device amount.

*4:

About the error status, please refer to the table 2-6.

*5:

About the CAN status, please refer to the table 3-1.

*6:

Writing the address (Max. AO address + n) to 1 will let the GW7433D send

a CANopen reset command to n

th

CANopen slave.

*7:

Writing the address (Max. AO address + N + 1) to 1 will let the GW-7433D

reboot.

*8:

Writing the address (Max. AO address + N + 2) to 1 will let the GW-7433D

into listen mode. If users want to recover to the normal mode, please write it to
0. About the details of “Listen Mode”, please refer to section 3.3.
