Serial Driver “ABB RS232 Route AC”¶
As of version V1.2.0, the serial routing driver “ABB RS232 Route AC” is available in addition to the serial driver. This driver provides the following functions:
- Online operation of the PLC with the Control Builder
- OPC connection with OPC server, as of version V1.2.0
- Online operation of PLCs connected via ETHERNET or ARCNET using the serial interface (Control Builder version V1.3 and later)
- Parallel operation of Control Builder and OPC server
To define a new gateway channel for the serial routing driver, select “Online/Communication Parameters” and press the button “New” in the “Communication Parameters” window. In the appearing window, enter a name for the channel (for example AC COM1 Route ARC 2) and select the driver “ABB RS232 Route AC” from the device list.
The following communication parameters can be set for the serial routing driver “ABB RS232 Route AC”:
| Parameter | Possible values | Meaning |
|---|---|---|
| Port | COMx (PC dependant) | Serial interface of the PC |
| Baudrate | 19200 | Always 19200 baud |
| Parity | No | Always no parity |
| Stop bits | 1 | Always one stop bit |
| Routing levels | 0…2 | Routing levels (0 = none) |
| Communication Module (Level 1) | 0, line 0…line 4 | Communication Module for level 1 |
| Channel (Level 1) | 0…19 | Channel on Communication Module level 1 |
| Address (Level 1) | 0, 0, 0, 0, 0 (max. 5 bytes) | Address in target Communication Module level 1 |
| Communication Module (Level 2) | 0, line 0…line 4 | Communication Module for level 2 |
| Channel (Level 2) | 0…19 | Channel on Communication Module level 2 |
| Address (Level 2) | 0, 0, 0, 0, 0 (max. 5 bytes) | Address in target Communication Module level 2 |
| Motorola byteorder | yes | Selection of Motorola or Intel byteorder |
If you want to use the serial routing driver in order to directly access the connected CPU, set all routing parameters (parameter Routing levels and following parameters listed in the table above) to 0.
Note
Routing is available with version V1.3.x of the Control Builder and PLC firmware.
The following applies to the routing levels:
Routing levels = 0 No routing (parameters for Level 1 and Level 2 not set)
Routing levels = 1 Single-level routing (set parameters for Level 1)
Routing levels = 2 Double-level routing (set parameters for Level 1 and Level 2)
Example:
Configuration of PLC 2 (IP: 10.49.88.205) shall be performed via the external ETHERNET Communication Module (IP: 10.49.88.203) inserted in slot 1 of PLC 1. The serial PC interface COM2 is connected to the serial interface COM1 of PLC 1:
| Parameter | Value | Remark |
|---|---|---|
| Port | COM2 | PC COM2 |
| Baudrate | 19200 | |
| Parity | No | |
| Stop bits | 1 | |
| Routing levels | 1 | Single-level routing |
| Communication Module (Level 1) | Line 1 | Communication Module in slot 1 |
| Channel (Level 1) | 0 | Channel 1 |
| Address (Level 1) | 10, 49, 88, 205, 0 | Subscriber address of the target PLC (Node 2) |
| Communication Module (Level 2) | 0 | No level 2 |
| Channel (Level 2) | 0 | |
| Address (Level 2) | 0, 0, 0, 0, 0 | |
| Motorola byteorder | yes | Motorola byteorder |
