Monitor the error information of each Slave Number
The error information of external devices communicated with using Sub Host Communication can be monitored per
external device.
This option is configured on the
Sub Host Communication tab in the Project Settings dialog box. Select the
Monitor the error information of each Slave Number check box, and then specifies a word device to write the
error information. 256 word devices from top device set in this option are used. Each device is assigned to each slave
number of PLC.

Address Settings” on page 2-70.
●
Keep running with skipping the Slave Number of communication error
When this option is selected, skip the slave number error has occurred and connect with next slave number. This
option is configured on the Sub Host Communication tab in the Project Settings dialog box. Select the Keep
running with skipping the Slave Number of communication error check box.
When this option is not selected, retry communication with same slave number until recover from the error.
Bit Function Descriptions
0 Connection
Specifies the communication with the external devices of the relevant slave
number.
When this bit is 1, MICRO/I connects with each external device. When this bit
is 0, MICRO/I does not connect the external device.
Default value is 1 when the device addresses of the relevant slave number
are registered to HMI Link Registers (LLR).
1 Reserved ―
2 Finish 1st reading
This bit changes to 1 after all device addresses allocated to HMI Link
Registers (LLR) of the relevant slave number are read.
3 Reserved ―
4 Current Error
This bit changes to 1 while the communication error occurs in the device
addresses allocated to the HMI Link Registers (LLR) of the relevant slave
number. This bit changes to 0 after the communication error recovers.
5 Reserved ―
6 Error Log for Reading
This bit changes to 1 when the reading error has occurred in any device
address allocated to the HMI Link Registers (LLR) of the relevant slave
number. This bit keeps 1 even if the reading error recovers.
Writes 1 to the Bit 1 (Initialize) of the Monitor the error information of
all Slave Numbers check box to make this bit 0.
7 Error Log for Writing
This bit changes to 1 when the writing error has occurred in any device
address allocated to the HMI Link Registers (LLR) of the relevant slave
number. This bit keeps 1 even if the writing error recovers.
Writes 1 to the Bit 1 (Initialize) of the Monitor the error information of
all Slave Numbers
check box to make this bit 0.
