1. Data Types of External Devices You Can Use

## Connection Configuration

IMPORTANT:

- When using more than one driver with one Display (except SP-5B10), there are the following limitations as listed below.

- The Modbus SIO Slave driver (communication speed: 38400 or more) of Modbus Organization cannot be used simultaneously.

- The DH-485 driver of Rockwell Automation, Inc. cannot be used simultaneously.

- The Uni-Telway driver of Schneider Electric SA cannot be used simultaneously.

- This driver cannot be used with both COM1 and COM2.

NOTE

- You can mix the S7-300/400 Series, the S7-200 Series and the S7-1200 Series to use in one connection configuration.
- It is not recommended to mix the DP corresponding device and the MPI corresponding device for one connection constitution.

- 1:1 Connection

- n:m Connection

NOTE

- For n:m connection, the unit number of Display and External Device needs to be within the range which satisfies the conditions below.

- You can connect max 64 units of the External Device to 1 unit of the Display.

- Maximum unit number of the Display that can be connected to 1 unit of the External Device varies depending on the type of the External Device. Please refer to the manual of each External Device for checking.

## Communication Settings

Examples of communication settings of the Display and the External Device, recommended by Pro-face, are shown.

WARNING

UNINTENDED EQUIPMENT OPERATION

Read and understand the instructions in this section to ensure data is properly transferred.

## Cable Diagram

The following cable diagrams may be different from cable diagrams recommended by External Device Manufacturer.

Please be assured there is no operational problem in applying the cable diagram shown in this manual.

- The FG pin of the External Device body must be grounded according to your country's applicable standard. Refer to your External Device manual for details.

- SG and FG are connected inside the Display. When connecting the External Device to SG, design your system to avoid short-circuit loops.

- Connect an isolation unit if the communication is not stable due to noise or other factors.

## Supported Devices

Range of supported device address is shown in the table below. Please note that the actually supported range of the devices varies depending on the External Device to be used. Please check the actual range in the manual of your External Device.

WARNING

UNINTENDED EQUIPMENT OPERATION

- Do not simultaneously write to the same register from Display and External Device program.
- Do not write 16-bit word values to registers being accessed in a bitwise manner.
