...
This protocol supports data reading and writing to the dataloggers INMAT 66 and INMAT 51 dataloggers produced by ZPA Nová Paka (Czech republic).
...
- Communication line category: Serial, SerialOverUDP Device Redundant.
- The parameters of an asynchronous line are set according to version and type of device connection:
- the settings from the manufacturer (you can find out it on a display in the control menu): 9600 Baud, 8 data bits, even parity, 1 stop bit.
Note:
When testing, we found out that there was a short period between sending the request and receiving the response (less than 10 ms). You should enter the similar values (1 to 10 ms) into the parameter "Receive delay" in the line mode. If there are several devices on one line (RS485), you should set such value which is suitable for all devices to ensure 100% success of data transfer.

Communication station configuration
...
- Communication protocol: ZPA INMAT 51/66.
- The station address is a decimal number in the range of 0 up to 126 (you can find it on a display of device).
- When necessary, you may enable the synchronization of real-time on the station – INMAT devices.

Station protocol parameters
...
Communication station - configuration dialog box - tab Protocol parameters.
They influence some of the optional parameters. You can set the following station protocol parameters:
Table 1
| Parameter | Meaning | Unit | Default value |
|---|
|
Delay reading until it is completed millisec.First waiting for response | The delay after sending the request and before reading the response. | ms | 200 |
millisec.Delay between the response retry if some error in communication occurs| Timeout before resending a request if no response has been received. | ms | 500 |
millisec.Maximum | The maximum number of retries of |
reading until it is completedNumber of response retries if some error in communication occurs| Maximum count of request retries. If no response returns after a request had been sent, the station's status will change to a communication error. | - | 2 |
|
Local | The local source address of the D2000 KOM process. | - | 0 |
| Communication monitoring high level, information about reading I/O tags, and received values are displayed. |
I/O tag configuration
...
I/O tags: Ai
For address, you must set two parameters:
INX and IY
These address parameters are provided by the producer (ZPA Nová Paka) when buying the device.
