9.3.2 UD Link
The UD Link provides communications with devices that communicate via RS232, RS422 or RS485. You can edit a
packet according to its communication format to send and receive packets. This section introduces the use of UD
Link communications in COM mode. Make sure the knob of SCM module is turned to 0 before operation. SCMSoft is
embedded in DCISoft. Go to www.deltaww.com
to download DCISoft V1.19 or later. And after that you can use
SCMSoft in ISPSoft.
The steps for creating a UD Link protocol communication are:
In HWCONFIG
Set up the function card. -> Set the communication protocol to UD Link. -> Set up the communication format and
baud rate. -> Download to HWCONFIG. -> Use data length 8 byte as the communication format, 8E1, 8N1, 8O2 and
so forth to ensure a complete transmission. After setting, right-click the module to open SCMSoft in HWCONFIG.
In SCMSoft
Upload the module parameters to UD Link. -> Right-click Group List to create a group list. -> Double-click the Group
List 1 to set up the slot number on the editing window on the right -> Right-click the created group list on the node to
create groups for data mapping. -> Define the Group ID and Group Name on the editing window on the right.
The slot number in the group list is the actual placement order of AS00SCM-A on the right-side of the PLC. For
example, the slot number 2 in the group list corresponds to the second module on the right-side of the PLC. Once the
group list is assigned to a certain slot, the CARD 1 and CARD 2 of its corresponding module can trigger the group list
of the selected slot. You need to create a new group list for different module that needs to use UD Link.
After the group list is created, you can edit packets for transmission.
Edit TX and RX packets. -> Create commands. -> Download parameters to UD Link. -> Download in groups and
once a group number is trigger, the function card starts to send and receive packets according to the comment order.
