CR#21: Triggering the sending/receiving of the packets in a group through COM1
[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#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.
CR#26: Base register used for the sending of data through COM2
[Description]
Please refer to the description of CR#22.
CR#27: Base register used for the receiving of data through COM2
[Description]
Please refer to the description of CR#23.
CR#28: Triggering the sending/receiving of groups of packets in sequence
[Description]
High byte: COM1; Low byte: COM2
The number of times the sending/receiving of groups of packets is triggered in sequence is written
into CR#28. If the value in CR#28 is 0, the sending/receiving of groups of packets is not triggered.
The number of times the sending/receiving of groups of packets is triggered in sequence is in the
range of 1 to 254. If the value in CR#28 is 255 (16#FF), the sending/receiving of groups of packets
is continually triggered in sequence.
CR#4099~CR#4114: Selecting Enable boxes to enable the reading of data from bit devices
through COM1
[Description]
Users can select Enable boxes to enable the reading of data from bit devices through COM1. They
can set 256 values (No. 1~No. 256) in bit devices in AH10/15SCM-5A.
