Remia E3
Remia E3 communication protocol
Supported device types and versions
This protocol supports data reading/writing from a controller of quarter-hour maximum Remia EEE.
Communication line configuration
Communication line category: Serial, SerialOverUDP Device Redundant, TCP/IP-UDP.
Parameters of the serial line:
Baud rate - 1200 Baud
No parity, 8 data bits, 1 stop bit
Parameters of UDP line:
Host: IP address of the controller
Port: UDP port of the controller where requests are sent.
Note: The parameters of the backup server (Host and Port) are not used in this protocol.
Communication station configuration
Communication protocol: Remia E3.
The station address is set according to the address on a device (0 to 15) specified as a decimal number or as a hexadecimal number with a hash at the beginning (e.g. #6A).
Station protocol parameters
The configuration dialog box of station - the tab "Protocol parameters".
Table 1
Keyword | Full name | Meaning | Unit | Default value |
|---|---|---|---|---|
RC | Retry Count | 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 |
RT | Retry Timeout | Timeout before resending a request if no response has been received. | ms | 100 ms |
WFT | Wait First Timeout | The delay after sending the request and before reading the response. | ms | 100 ms |
WT | Wait Timeout | The delay between the response readings. | ms | 300 ms |
MWR | Max Wait Retry | The maximum number of retries of the response reading. | - | 10 |
I/O tag configuration
I/O tag types: Ai, Ci, Co, Di, TiA, TiR.
The address is a number in the range from 0 to 300 (as a decimal number or as a hexadecimal number with a hash at the beginning, e.g. #0A).
The meaning of the addresses is stated in Table 2:
