Allen-Bradley device driver | SKTool Manual | Factonation

Allen-Bradley

The device driver is used for SK series HMI to read and write the data or state of AIBUS device via AIBUS protocols. The serial communication connection is established through the serial port of the HMI and the serial port of AIBUS device, so as to operate AIBUS device. Prior to use of the driver, please carefully read this chapter and the related technical specifications of the AIBUS device.

How to establish connection with AIBUS device

1. Hardware connection

Connecting cable:

RS232 (serial port RS232 protocol)

SK HMI COM1/COM2		AIBUS device
2	RX	User-defined pins	TX
3	TX	User-defined pins	RX
5	GND	User-defined pins	GND

ControlLogix/CompactLogix:

SK HMI COM1/COM2		Allen-Bradley（AB）
2	RX	3	TX
3	TX	2	RX
5	GND	5	GND

SK HMI port is DB9F, and AB device port is MD8M.

2. Software settings

ü Select Allen-Bradley in connection device service.

ü Select the corresponding item in connection device service according to the connected PLC model or supported protocol.

ü Ensure that the communication parameters in touch screen connection parameters and PLC station number are consistent with the PLC connected.

ü For settings of the PLC connected device, refer to the technical documents of the Allen-Bradley PLC.

PLC new address label

Address tag correspondence

The register label type array size

B bool 255

I int 255

F real 100

The label format must be 3 characters, such as B003,I004, and F005

Connect the 1766 series MicroLogix DF1_TCP

Except I/O register cannot be set to size, other register array size is set to 256,The first file number in the address input format is the file number. For example, the file number of F8 is 8, the file number of I1 is 1, and so on.
