Summary
Omron Host Link implements communication CPU Units that are compatibles with C-mode commands via Host Link. The communications blocks are dynamically created according to the pooling cycle defined on the Access Type for each Device Point.

Channels Configuration
Protocol Options
- Max Block Size: Determines the maximum block size. Default is 29 Word Addresses
- Ignore Non Critical Error: Indicates the driver behavior when the PLC returns the 64 status that is a non fatal error:
- True: returns Success, with error code = 64 and set the tag quality to GOOD
- False: returns Failed, with error code = 64 and set the tag quality to BAD
- Change the PC mode for Writings: Indicates whether the communication driver should send a command that changes the PLC state to MONITOR in order to perform writing operations, otherwise the writing will fail (error code 1). Default = True
Settings - Serial channels:
Default RS-232 serial port configuration.
Nodes Configuration
Station Configuration - Serial (RS232) Channels
Syntax: <Device id>
Where:
- <Device id> is the PLC address.
Station Configuration - Multi Serial channels:
Syntax: <Port> ; <Device id>
Where :
- <Port>: COM port for communication (default is COM1)
E.g.: COM1 ; 0
Points Configuration
The syntax for the communication points is: <Memory Area> : <Address>
The Valid Memory areas are:
Valid Memory Areas |
|---|
IR – Internal Relay |
SR – Extended Relay |
HR – Holding Bit |
AR - Auxiliary Bit |
DM – Data Memory |
PV – Timers/Counter Value |
TC – Timer/Counter Status |
E.g.:
| Examples | ||
|---|---|---|
| Syntax | Memory Area | Address |
CA:0 | CA | 0 |
| CIO:20 | CIO | 20 |
| EM0:1 | Extended Memory 0 | 1 |
| EM6:1 | Extended Memory 6 | 1 |
