How to check the communication condition between the temperature controller and the V/TS

Category :

GLOBAL > HMI > V8/TS2060 series > Questions about

Answer

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.

Error details

Code (HEX)	Description
0000H	Normal
FFFH	Timeout
8001H	Check code error
8002H	Data error
800BH	Error code received from the connected device *

* The received code can be acquired at $Pn: 508 to 511. For more information, click here.

Other error codes are shown below:

Error	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.
