01 Introduction, general information
Technical specifications
It is a well-known fact that when building CNC machines with
apply of PC and MACH3 program, a common problem occurs with
existence of necessary number of free inputs/outputs for limit
sensors, buttons and external load connection. The problem caused
in the first place by the fact that PC LPT-port (the port through
which MACH3 operates the machine) has only 12 output lines and 5
input lines which is not enough for building a full-featured CNC
machine. To solve the problem you can connect extenders of
input/output lines to the system which collaborates with MACH3
through COM-port (or USB port using COM>USB adapter) under
protocol MODBUS. MACH3 supports MODBUS devices.
PLA001mb is output lines expander, 8 independent relays
controlled from MACH3 through COM-port (or USB-port using
COM>USB adapter) under protocol MODBUS.
PLA002mb is input lines expander, 8 independent optoisolated
inputsare registered by MACH3 through COM-port (or USB-port using
COM>USB adapter) under protocol MODBUS.

MACH3 installation for module operation
03. Module connection
Press ‘Apply’ button, then ‘OK’. Be sure to restart MACH3.In the
‘Settings’ window of Function Cfg`s/Setup Serial Modbus Control it
is necessary to perform support setting of module PLA001mb, set the
parameters as it is shown below:
Now it is necessary to correlate output signals of MACH3 with
relay K1...K8 on PLA001mb board. MODBUS port in MACH3 is “0” port.
Relay “K1” is “Pin #7” …Relay “K8” is “Pin #0”.Example of signal
setting Output#1 = K8 … Output#1 = K1 is shown below:
Connection of module PLA001mb is performed according to
fig.1Module PLA001mb is connected to COM-port of PC through a
standard connector DB-9 XP11 or through COM>USB adapter (it is
purchased separately, not included in the set). Module PLA001mb has
inbuilt rectifier of alternating voltage therefore as a power
source you can use direct current source 12V or alternate current –
9V.The voltage is connected to XP9 or XP10, polarity of connection
is not important.We recommend to use 12V source of the PC as a
voltage source.Power loads are connected to XP1...XP8, relay action
K1...K8 is indicated by HL1...HL8 LEDs.
Start MACH3. In the “Settings” window of Config/Ports and Pins
turn on ModBus InputOutput Support, according to the figure:

04. MACH3 installation for module operation
When changing Active Low state with help of a mouse for set
Output #1 … Output #8, you can be sure of the set device
operation.
The warranty period is 12 months after purchasing and is valid
only if all operational conditions and scheduled maintenance are
strictly followed.
