How to check the communication condition between the temperature controller and the V/TS
The temperature controller condition is output to the system device memory of the V/TS.
Check the following addresses for each station number.
[V8/TS]
Select [System Setting] → [Hardware Setting] → [PLC n] → [PLC n Properties] on the V-SFT editor and select [Stop] for [Comm. Error Handling].
The communication results with each station are stored in the system device memory as below.
Assign system device memory addresses to numerical data display parts for monitoring.
System device memory: $Pn: 100 - 355 (n: PLC1 - 8) ..... Station No. 0 - 255
Example: When a temperature controller is registered to PLC2 as station No. 10, monitor $P2: 110.

Details |
Solution |
| Timeout | Although a request to send is given, no answer is returned within the specified time. | Take actions 1, 2, and 3. |
| Check code | The response check code is not correct. | Take actions 1 and 3. |
| Data error | The received code is invalid. | Take actions 1, 2, and 3. |
| Error code received | An error is occurring at the connected device. | Refer to the PLC manual. |
| Buffer full | The buffer of the V series is full. | Contact your HAKKO representative. |
| Parity | A parity check error has occurred. | Take actions 2 and 3. |
| Overrun | After one character is received, the next character is received before internal processing is completed. | Take actions 1 and 3. |
| Framing | Although the stop bit must be "1", it is detected as "0". | Take actions 1, 2 and 3. |
| Break detection | The SD of the connected device remains at the low level. | Check connection to the SD/RD of the connected device. |
[Measures]
- Check that communication settings of the V/TS match those of the connected device.
- Check the cable connection.
- Data may be disrupted because of noise. Provide protection against noise.
[V7 series]
The communication results with each station are stored in the system device memory as below.
Assign system device memory addresses to numerical data display parts for monitoring.
System device memory: $s: 730 - 761 ..... Station No. 0 - 31
Example: When a temperature controller is station No. 10, monitor $s740.
Error details
Refer to [V8/TS].
