On-Site Operation Panel for Surface-Mounting Housing (Port H) (Available only for Modular Devices)
The terminal for the on-site operation panel of surface-mounted devices is located on the D-sub 15 interface
(position H). The on-site operation panel of surface-mounted devices with integrated or detached on-site oper-
ation panel is connected to this interface.
