5.6.- COMMUNICATION CONNECTION DIAGRAM
M-BASE has 3 built-in communications ports that can send the information from the connected
modules to external devices. The ports are as follows:
• RS-232
• RS-485
• ETHERNET (TCP/IP)
The 3 communications ports operate as independent systems. In other words, they can simultaneously
request information from all connected modules.
5.6.1.- RS-232
QNA 500 system is supplied with an RS-232 communications cable. The cable wiring diagram is as
follows:
The RS-232 communications port can be used to access the different modules connected to the M-
BASE module. Each module has a peripheral number (default: M-BASE = 01, M-QNA500= 02 and M-
8IO = 10, M-8IOR=10), which must be taken into account when establishing communications.
