【#29063(PR)】 Bus Error Counter Bus error counter
Set a device to store the following data:
- The number of times that the illegal frame count of the CAN chip (DeviceNet's communication chip)
exceeded 96 is stored. When this value is large, it indicates that communication is unstable.
---Setting range---
Within the number of device points set in the PC parameter's device setting.
【#29064(PR)】 Bus Off Counter Bus off counter
Set a device to store the following data:
- The number of times that the QJ71DN91 makes a transition to the Bus-off status is stored. When
this value is large, it indicates that communication is unstable.
---Setting range---
Within the number of device points set in the PC parameter's device setting.
【#29065(PR)】 Node Configuration Status Module side Transfer Cont.
Each node configuration status read word count
Set a read word count of the data where the slave node parameter settings are saved.
The standard setting is "4".
---Setting range---
0 to 4
【#29066(PR)】 Node Configuration Status PLC side Device
Each node configuration status read device
Set a device to store the following data:
Set the device where the slave node parameter settings are saved.
Bit settings 0: Parameter setting is not complete/ 1: Parameter setting is complete
<1st word>
bit0: 0th slave node
bit1: 1st slave node
:
bitF: 15th slave node
<2nd word>
bit0: 16th slave node
bit1: 17th slave node
:
bitF: 31st slave node
<3rd word>
bit0: 32nd slave node
bit1: 33rd slave node
:
bitF: 47th slave node
<4th word>
bit0: 48th slave node
bit1: 49th slave node
:
bitF: 63rd slave node
(Note) The bits' ON/OFF timing
---Setting range---
Within the number of device points set in the PC parameter's device setting.
When one of the followings has been executed and parameter check is completed, the bit
corresponding to the specified slave node will be turned ON.
- Start the I/O communication.
- Save the master function parameters into the flash ROM.
Executing the above after cancelling the slave node setting in the master function parameter
turns OFF the corresponding bit.
All bits will be turned OFF when the master node is turned OFF and ON or when the CPU
module is reset.
