Configure settings to communicate with the device/PLC using scripts.
Type
Select [D-Script/Global D-Script] to use the "SIO Port Operation" function, which communicates using a serial port for D-script or Global D-script. Select [Extended Script] to use extended scripts.
Port
Select the port used for scripts: [COM1], [COM2], [USB/SIO(RS232C)], or [USB/SIO(RS422/485)].
If the port is also used for other devices/PLCs, 
is displayed to the right of the [Port].
You can select [USB/SIO (RS422/485)] for the SP5000 Series (excluding Open Box) and the GP4000 Series (excluding GP-410*).
Communication Settings
Configure communication settings.
This is not displayed when the [Type] is [Do Not Use].
[Communication Settings] differ depending on the device/PLC selected. For details on the settings of the device/PLC, see "GP-Pro EX Device Connection Manual."
Communication Settings
Select the communication method from [RS232C], [RS422/485 (4wire)], or [RS422/485 (2wire)].
Speed
Select a communication speed from [1200], [2400], [4800], [9600], [19200], [38400], [57600] or [115200].
[1200] can be set when using extended script and the [Port] is selected in [USB/SIO(RS422/485)].
Data Length
Choose the communication data length from [7 bit] or [8 bit].
Parity
Select the communication parity bit from [None], [Odd], or [Even].
Stop Bit
Choose the communication stop bit length: [2 bit] or [1 bit].
Flow Control
If the communication method is [RS232C], select the communication control method from [None], [RTS/CTS] or [ER (DTR/CTS)].
When [Port] is [USB/SIO(RS232C)], [Flow Control] is set to [None].
When [Port]=[USB/SIO(RS422/485)], this property is hidden.
The Extended Script's wiring diagram for connections between the display unit and device/PLC will vary depending on the [Flow Control] settings and the [Flow Control] set up in the device/PLC's [Communication Settings]. For more details, please refer to the following.
22.5.2 Structure of Extended Scripts
5V Power Supply
If the communication method is [RS232C], designate whether or not to specify the 5V power supply. Only set it to [Enable] if the connected device requires a power supply. If a 5V power supply is not needed and you select Enable, damage can occur to the connected device or the display unit. Confirm the specifications of the connected device and cable before setting this.
When [Port] is [USB/SIO(RS232C)], this setting is [None].
When [Port]=[USB/SIO(RS422/485)], this property is hidden.
