X10RF Control
WebControl uses TTL7 and TTL8 to control X10RF devices. User must already
enabled X10RF function in the I/O Setup screen. An external RF transmitter must be
attached to the output port TTL7, TTL8, and ground. In the USA, the X10 RF
frequency is 310MHz, and in Europe, the frequency is 433 MHz WebControl can
send all 16 house codes and 16 unit codes, controlling total 256 devices.
X10 RF function is supported in the PLC programming also.
In PLC programming, PLC command is in the format:
X10
H
U
C
Where H is house code from 0-15, U is unit code, also from 0-15; C is one of
following four commands: 0 – Off, 1 – On, 2 – Bright, 3 – Dim. H,U,C can be
variables so that user can dynamically change the X10 operation in PLC logic.
If the X10 function enabled, TTL7 and TTL8 should not be used for controlling other
devices. Please note PLC logic uses 0-15 or 0-0xF for code, web GUI only use 0-F.
