AH500 Module Manual CR#8 : Triggering the writing of data through COM1 [Description] High byte: Writing data into bit devices; Low byte: Writing data into word devices 0: Not triggering it; 1: Triggering it once; 2: Always triggering it After 1 or 2 is written into CR#8, the writing of data through COM1 will be triggered. After 0 is written into CR#8, the writing of data through COM1 will stop. Please refer to the table in the description of CR#7. CR#17 : Triggering the reading of data through COM2 [Description] High byte: Reading data from bit devices; Low byte: Reading data from word devices 0: Not triggering it; 1: Triggering it once; 2:
Always triggering it After 1 or 2 is written into CR#17, the reading of data through COM2 will be triggered. After 0 is written into CR#17, the reading of data through COM2 will stop. Please refer to the table in the description of CR#7. CR#18 : Triggering the writing of data through COM2 [Description] High byte: Bit; Low byte: Word 0: Not triggering it; 1: Triggering it once; 2: Always triggering it Please refer to the table in the description of CR#7. [Description] After a group number is written into CR#21, the packets in a group will be sent/received through COM1. After 1 is written in CR#21, the sending/receiving of the packets in group 1 will be triggered.
After the sending/receiving of the packets in group 1 is triggered, the value in CR#21 will become 0. Default: 0 (Not triggering the sending/receiving of the packets in any group.) CR#21 : Triggering the sending/receiving of the packets in a group through COM1 CR#22 : Base register used for the sending of data through COM1 [Description] The communication protocol for exchanging data through COM1 must be UD Link. Users have to select Base+Offset in the Mapping Register box in the Message Variable Edit widow in SCMSoft. Data register from which data is read=Value in CR#22+Offset Example: The value in CR#22 is 1.
D1 Base+Offset in the Mapping Register box in the Message Variable Edit widow in SCMSoft is selected. The offset is 10, and the length is 2. (R (Base+Offset [10]), 2) D (1+10) Two-byte data is read from D11. CR#23 : Base register used in the receiving of data through COM2 [Description] The communication protocol for exchanging data through COM1 must be UD Link. Users have to select Base+Offset in the Mapping Register box in the Message Variable Edit widow in SCMSoft. Data register into which data is written=Value in CR#23+Offset CR#25 : Triggering the sending/receiving of the packets in a group through COM2 [Description] Please refer to the description of CR#21. 8-10
