## Connection Configuration

- 1:1 Connection

- 1:n Connection

NOTE

- Maximum number of External Devices is 64.

- n:1 Connection

NOTE

- The maximum number of Displays varies depending on the External Device series and the settings.

- When TOYOPUC-PC3 is used, up to 8 Displays can be connected.

- When "Ethernet" is specified for L1/L2 port settings on the CPU unit in TOYOPUC-PC10G, up to 8 Displays can be connected.

- When "Ethernet (32 ports)" is specified for L1/L2 port settings on the CPU unit in TOYOPUC-PC10G, up to 32 Displays can be connected.
  "Ethernet (32 ports)" can be specified only when the CPU version is V.3.00 or later.

- When using THU-5296/THU-5781 in TCP connection, you can connect max 8 units of the Display to 1 External Device.

- n:m Connection

- Maximum number of External Devices is 64.

- FL-NET Connection

You can use this driver to access up to 4 layers of External Device connected to FL-NET.

In the [Protocol Configuration] menu, in hierarchical order, set up the program number / link number of External Device that act as relays, and the destination External Device's node number.

Example [Protocol Configuration] with the following network structure.

Set up each connected piece of External Device (such as A1 and X1 shown in the figure) using the ladder software PCwin. Display the [Link parameter setup] dialog box and set up the program number / link number and node number of the port to connect to FL-NET.

## 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.

NOTE

- Select the series from the driver property of BLUE. Normally select "AutoDetect".

[AutoDetect]:
Automatically changes communication commands based on whether the External Device is using "PC3 / PC10 Standard mode" or "PC10 mode".

[PC3/PC10 Standard mode]:
Use communication commands supported by "PC3 / PC10 Standard mode". You can use the "PC3 / PC10 Standard mode" address range.

[PC10 mode]:
Use communication commands supported by "PC10 mode". You can use the address range.

## Supported Device

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.
