• The controller has 3 ports. The first port is presented by XS3.
connector. It is buffered and is similar to LPT-port according to
assignment and contacts numeration (fig. 2).
1. Turn on the controller and connect it to Ethernet.
Link LED must flash on. If it does not or blinks and network connection
icon appears/disappears in Windows, automatic type definition went
incorrect (this was caused by special features of some network cards).
In this case it is necessary to set up manually. Click on the [Start] icon-
[Control Panel], [Network and Sharing Center], Local Area Connection
– properties. Then press ‘configure’ (fig. 4). In ‘Advanced tab’ choose
‘Speed and duplex mode’ and set ‘10Mbit per second full duplex’ (fig. 5).
(Parameters and names can slightly differ in different network cards).
2. For device work with MACH3, you need to install plug-in.
Please download zip-file for PLCM controllers from here:
www.purelogic.ru/files/downloads/SOFT/PLCM.zip and run «setup.
exe». Software installation wizard for controller will be started. (fig. 4).

Fig. 8. Plug-in option
Fig. 9. Device option / Plug-in setup in MACH3
Controller automatic search can disrupt local network, use this
function only if you do not use local network resources on the PC and
do not use the Internet. Press ‘Next’, then ‘Install’. The master will copy
the necessary files and finish its work.
3. Having installed the plug-ins, when starting MACH3 choose the
appropriate plug-in in the window which is shown in fig. 9.
As a rule there are two versions of plug-ins for PLCM controllers: test
and stable.
Choose the one you are going to work with. Tick ‘Don`t ask me
again ‘ in order not to choose it every time. If there is necessity to
change output device choose: MACH3 – Function Cfg’s – Reset device
sel.
* If you decided to go to another version (test or stable version, you will
need to go to plug-in setting up after start-up (see further) and update
internal controller software.
4. After successful plug-in start, PLCM control option will appear in
menu MACH3 PlugIn. Choose this option.
* If you see the window as it is in fig. 8 and you cannot choose controlling
device, this means that Windows firewall blocks access to PLCM-E1b.
You must either add MACH3 to firewall exception or disable firewall.
5. Execute plug-in setting.
Out of a falling out list it is necessary to choose one of the controllers
connected to the system.
After choosing the option additional controller settings will be available
(fig. 11). If the plug-in finds that weaving is out of date, you will be
prompted to update weaving in the controller. This procedure needs to
be performed once when first device installation.
Settings description:
Advance path planning time of Mach3 – specifies data size about motion
path, which the program needs to prepare beforehand. The more the
value, the more stable the machine works (e.g. when ToolPath picture
rotates , Mach stops calculating new trajectory data, therefore the
more of them were calculated beforehand, there is the less possibility
of ‘failure’ in motion while rotating the picture or some other load on
Mach3).

05. Software installation
Time of advance calculation of path of PLMach – similar buffer,
not from Mach3 side, but in PLCM card. The buffer stabilizes the
work under short lineouts PLCM<>Mach3 and under slowing down
calculation of Mach.
Note: From one side the more value of these features, the better (the
buffer is bigger, the work is more stable) but with increase of buffer
FeedHold will be delayed by the sum of these parameters, i.e. If
Mach3 buffer=1 sec and PLMach buffer=0,5 sec, CNC-system reaction
time when pressing FeedHold =1,5 sec + stepper motor braking time
according to the defined acceleration profile.
Logging – with active logging, log exchange file PLCM<>Mach3 is saved
to ‘C:\Mach3\
PLСM.log’. When exploring incorrect device work, this file must be
sent to Purelogic R&D technical Support with the detailed problem
description. To receive IP-address automatically we recommend to
leave this item active, if there is a device which can dynamically assign
IP-addresses (e.g. it can be a usual home network gateway for internet
connection )in you local network
Receiving address from DHCP-server – we recommend to make this
item active, if there is DHCP-server in your local net (device which can
dynamically set IP-address, it can be a common home network gateway
for access to the Internet).
Usage of the following IP-address – this option must be used when
there is no DHCP-server which appoints IP-addresses.
Restore IP button allows to reset IP-address of controller to those
installed by default.
If the controller is not found by the plug-in, follow the instructions in
item 6, if it is ok, skip item 6.
6. Automatic setting of network connection.
There is a complete solution for quick and easy configuration network
setting.
In (C:\Mach3\Purelogic), supplied with the devise you will find set_
ip.exe file.
After starting, this application will set up of your PC network
connections.
In case when there are several network cards are installed (several
network connections) the program will offer to specify for what
connection to change the settings.
FOR CORRECT WORK WITH PLCM CONTROLLER IT IS NOT
RECOMMENDED TO PUT THE SWITCH IN AUTOMATIC POSITION.

05. Software installation
You can assign any address to your PC (e.g. 192.168.10.XX,
192.168.10.1.) The last value can be different different from 10, 11
and 12 (192.168.10.10 and 192.168.10.12 addresses for PLCM devices
established by the manufacturer.
Automatic address assignment installation will work with the controller
only when there is local DHCP server in the net. In all other cases the
controller will not contact the plug-in.
After necessary connection option and pressing the button install the
application apply required connection parameters.
After the installation the application will come with a message:
Choose the connection which you intend to use with PLCM. (In this
case it is meant that if the computer has several network cards, you
can install one of them for work with PLCM and the other one use at
your discretion. We do not recommend to apply this approach in work
mode, as system loading of third party applies can cause delay of
tasks execution in Mach3 which can lead to loosing connection with
the controller. You can use several network cards when testing and
setting the system). With help of Double click of left mouse button open
‘network properties’ window.
Choose Internet protocols TCP/IP and press Properties.
In the opened window displace the switch to ‘Use this IP-address’
mode.
Enter any address like 192.168.10.XX in IP-address line, e.g.
192.168.10.1. The last number can be any but differ from 10, 11 and
12 (192.168.10.10 and 192.168.10.12 addresses for PLCM devices
established by the manufacturer). Net mask is 255.255.255.0. After
pressing OK you will need some time to apply the parameters. Switch
off firewall and anti virus software (or add MACH3 to exceptions).
(After pressing the button ‘install’ the application will require 2-3
minutes for introduction of changes. On ‘slow’ PC this procedure
will take a little more time). If for some reason you failed to make
connection to PLCM controller in automatic mode, produce setting
manually. Click on the [Start] icon-[Control Panel], [Network
connection].
