Creating a Remote block of I/O:
Remote blocks of I/O are equipment connected to A through a communication port (RS485,
RS232, modem, …).
From the moment a A needs to communicate with other equipment, the latter become part
of its Resources. The A being Master and the Remote equipment Slave(s).
The A communicates to Remote equipment with the help of ‘Remote Tags’ (see chapter 14:
‘Remote Tags’).
When creating such equipment you must specify the following parameters:
Example for a ‘Remote TBox’:

Master A and possible other equipment on the same network.
• RTU Port: the communication port used by the Master to communicate with the equipment.
• IP address: in case the communication port of the Master is COM6 (Ethernet card), the IP
address of the Remote equipment must be specified here.
