8 4 Setup Items Set the communication settings of the Display with GP-Pro Ex or in off-line mode of the Display. The setting of each parameter must be identical to that of the External Device. "3 Example of Communication Setting" (page 6) 4.1 Setup Items in GP-Pro EX Communication Settings To display the setting screen, select [Device/PLC Settings] from [System setting window] in workspace. Unit ID Setup Items Setup Description Use an integer from 1 to 64 to enter the unit ID of the Display. GP-Pro EX Device/PLC Connection Manual 8

9 Device Setting To display the setting screen, click ([Setting]) of External Device you want to set from [Device-Specific Settings] of [Device/PLC Settings]. To connect multiple External Devices, click from [Device-Specific Settings] of [Device/PLC Settings] to add another External Device. [Equipment Configuration] tab Setup Items Equipment Address Bit manipulation [set/ reset] on Holding Register Reset of the bits in this word IEC61131 Syntax Double Word word order Setup Description Enter the slave address of the External Device. If the communication is routed through External Devices, you need to enter their station addresses from the left. For example, if the communication is routed through the External Device with Station Address 6 to that with Station Address 2 on another network, enter "6", "2","0", "0", "0" in [Equipment Address] from the left. [Equipment Address] consists of five levels. Enter "0" for unused ones. In the above example, "0" is entered in the three boxes on the right because the communication is routed to the second-level External Device. Select how other bits in the same word are handled when you manipulate bits in the holding register, from "Clear" or "Do not clear". Check this item when you use the IEC61131 syntax for variables. If you check this item, select the address mode from "0-based" or "1-based". Select the order of checking double word data from "Low word first (L/H)" or "High word first (H/L)".

(Page 1/2) Setup Items Equipment Address Bit manipulation on HR IEC61131 Syntax Double Word word order Setup Description Enter the slave address of the External Device. If the communication is routed through External Devices, you need to enter their station addresses from the top. For example, if the communication is routed through the External Device with Station Address 6 to that with Station Address 2 on another network, enter "6", "2","0", "0", "0" in [Equipment Address] from the top. [Equipment Address] consists of five levels. Enter "0" for unused ones. In the above example, "0" is entered in the three boxes on the lower side because the communication is routed to the second-level External Device. Displays how other bits in the same word are handled when you manipulate bits in the holding register, as "Rest of bits in word are cleared" or "Rest of bits in word are not cleared".
