Slave Function Comm.Status PLC side Device Slave function communication
status
Set the device to store the following data:
Slave function I/O communication status is stored.
00(HEX): OFFLINE; being initialized; bus-off; network power OFF
40(HEX): STOP; I/O communication being stopped
80(HEX): READY; waiting to establish the connection from the master node
C0(HEX): OPERATE; I/O communication in progress
The communication status above varies according to the auto communication start setting (address:
0631H):
- When "0: Not automatically start" is set:
Turning the power ON automatically changes the status from OFFLINE (00(HEX)) to STOP
(40(HEX)).
Turning ON the I/O communication request (Y11) changes the state to OPERATE (C0(HEX)).
However, the status is READY (80(HEX)) until the I/O communication request is received from the
master node.
- When "1: Automatically start" is set:
Turning the power ON automatically changes the status from OFFLINE (00(HEX)) to OPERATE
(C0(HEX)). However, the status is STOP (40(HEX)) until the I/O communication request is
received from the master node.
If a reset message is received from the network, the status automatically returns to OFFLINE
(00(HEX)) and makes transitions from OFFLINE (00(HEX)) to OPERATE (C0(HEX)).
---Setting range---
Within the number of device points set in the PC parameter's device setting.

Slave Function Error Inform. PLC side Device Slave function error information
Set a device to store the following data:
<Higher byte>
The communication error code occurred in the slave function is stored.
<Lower byte>
The node No. (MAC ID) of the node where the error occurred is stored.
FE(HEX), FF(HEX) (254, 255): Local node (QJ71DN91)
00 to 3F(HEX) (0 to 63): Node No. (MAC ID) of the node where the error occurred.
---Setting range---
Within the number of device points set in the PC parameter's device setting.

Master Func. IO Addr. Area Module side Transfer Cont.
Master function I/O address area read word count
Set a read word count of the data which stores the head address and the size (in word form) of the
master function receive and transmit data used by each slave node.
The standard setting is "252".
---Setting range---
1 to 252
