Networking Capabilities
Up to 31 text displays (both PX types) can be networked and driven through a PC or PLC.
You will need:
• Transmitter with RS 485 interface OR a V24 with V24 - RS 485 interface adapter
• One interface adapter (PAP) per PX-unit, RS 485 to V24 standard.
Each text display in the PX-network can then be driven via a configurable display address
stored in the text memory.
Example for networking 3 text displays to an RS 485-Bus via a PAP interface adapter.
It is not possible to operate networked displays in monitor mode.
Important! Please ensure that the controller is programmed to switch the interface from
send to receive as quickly as possible (within 1 ms) after a telegram is sent.
