1:1 Connection
1:n Connection
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.
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.
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.

The following description explains the memory maps for each parameter.
<When using Bit Data>
Bit Data (Read Only) : Function [02H]
| Relative Address | Coil No. *1 | Type | Memory Contents | Read-out Data |
| 0000H | 10001 | Bit | Alarm1 ON/OFF | 0: Alarm1 OFF 1: Alarm1 ON |
| 0001H | 10002 | (Reserved) | ||
| 0002H | 10003 | (Reserved) | ||
| 0003H | 10004 | (Reserved) | ||
| 0004H | 10005 | Bit | Alarm2 ON/OFF | 0: Alarm2 OFF 1: Alarm2 ON |
| 0005H | 10006 | (Reserved) | ||

*1 Coil No. is the address that is assigned by the Display.
Example: For the parameter "Alarm1 ON/OFF" of Coil No. 10001, the Display's designated address is as follows. Use the first digit of the Coil No. (00001 -, 10001 -) to designate the device.
Example: For the parameter "front surface control SV data" of Register No. 41003, the Display's designated address is as follows. Use the first two digits of the Register No.s (30001 -, 40001 -, 31001 - and 41001 -) to designate the device.
The External Device's
parameter data, when data transfer is performed, will have no
decimal places. Thus, in the Display, processing need to be performed
to correct the data. For example, if a numeric display is used
that includes decimal places, the "No. of Decimals"
of the "Display" settings need to be used. Also, when
writing data to a External Device,
it is necessary to write decimal values as integers.
Example: Register No. 41025's "Output 1 Lower Limit"
External Device
value/Setting Value : 3.00%
Display
value/Setting Value: 300
Please refer to your External Device
manual for details (with/without a decimal point) about data item
setting value ranges.
