2 Overview
PRM extension module provides additional inputs and outputs for the basic device PR200. The
module inputs and outputs are controlled by a program running on PR200. To enable control, the
module should be added to the PR200 configuration in ALP (sect. 4).
The module is a passive device and cannot be used without connection with the basic device over
internal bus.
All modifications are designed in a plastic enclosure for DIN rail mounting.
Each PRM module is powered independently of the basic device. The basic device and the modules
can be operated with different supply voltages.
2.1 Intended use
Extension modules of PRM series have been designed and built solely for the intended use
described in this manual, and may only be used accordingly. The technical specifications contained
in this manual must be observed.
The module may be operated only in properly installed condition.
Improper use
Any other use is considered improper. Especially to note:
– This device should not be used for medical devices which receive, control or otherwise affect
human life or physical health.
– The device should not be used in an explosive environment.
– The device should not be used in an atmosphere with chemically active substance.

4 Installation
WARNING
Electric shock could kill or seriously injure.
All electrical connections must be performed by a fully qualified electrician.
Ensure that the mains voltage matches the voltage marked on the nameplate.
Ensure that the device is provided with its own power supply line and electric fuse.
CAUTION
The device must be powered off before connecting to internal bus or peripheral
devices. Switch on the power supply only after the wiring of the device has been
completed.
Remove the terminal blocks only after powering off the device and all connected
equipment.
Do not feed any external devices from the power contacts of the device.
NOTICE
Supply voltage for 24 VDC models may not exceed 30 V. Higher voltage can damage
the device.
If the supply voltage is lower than 19 VDC, the device cannot operate properly but will
not be damaged.
NOTICE
Signal cables should be routed separately or screened from the supply cables.
Shielded cable should be used for the signal lines to ensure the EMC precautions.
NOTE
Before switching on, make sure that the device was stored at the specified ambient
temperature (-20 … +55 °C) for at least 30 minutes.
The extension module of PRM series are mounted on DIN rail to the right of the PR200 basic device.
Fig. 4.1
After mounting on DIN-rail, an internal bus connection between PR200 and the module should be
implemented (Sect. 4.1). Then the power supply and the peripheral devices should be connected to
the module terminal blocks (Sect. 4.2).
For dimension drawing see Appendix A..
4.1 Internal bus
An internal high-speed bus provides the same high-speed performance of the module that of the
basic device. It allows reading of the input values and writing of the output values of the module
within one program cycle.
The PRM modules are connected to PR200 in series. Maximum two modules can be connected. To
implement the internal bus, connect PRM to PR200, using the supplied 4.5 cm flat cable.
PRM has two EXT connectors located under the right and left covers on the device front. The
connector under the left cover is used to connect the 1st PRM to PR200 or the 2nd PRM to the 1st
one. The connector under the right cover is used to connect PR200 to the 1st PRM or the 1st PRM
to the 2nd one.

akytec GmbH - Vahrenwalder Str. 269 A - 30179 Hannover - Germany Tel.: [phone] - www.akytec.de
When connected, the flat cable should be placed in a special recess under the cover to enable PRM
to be pushed close to PR200 (Fig. 4.2).

4.3 Quick replacement
PRM is equipped with plug-in terminal blocks which enable quick replacement of the device without
disconnecting the existing wiring.
To replace the device:
1. Power off all connected lines including power supply.
2. Remove all detachable parts of the terminal blocks
3. Replace PRM
4. Connect detachable parts with existing wiring to the device

5 Configuration
11
akytec GmbH - Vahrenwalder Str. 269 A - 30179 Hannover - Germany Tel.: [phone] - www.akytec.de
5 Configuration
To add a module to the basic device configuration:
1. Open a PR200 project in ALP.
2. Open Device configuration.
3. Select the item ‘Extension modules’ in the structure tree.
4. Add PRM module using the context menu (Fig. 5.1)
Fig. 5.1
The parameter Extension number (Fig. 5.2) is the position of PRM, when counting from left to right
from PR200. The next module to the left of PR200 should be added to the configuration first to be
assigned as No.1. The next added module is always assigned as No.2. If there is no module
assigned as No.1, a new module cannot be assigned as No.2.
Fig. 5.2
Data exchange between PR200 and PRM No.2 is carried out
through PRM No. 1. If PRM No.1 is powered off, the data
exchange between PR200 and PRM No.2 is interrupted.
PRM can be removed from the project only after disconnecting
all the variables assigned to its inputs and outputs.
The position of PRM in the configuration can be changed using
the context menu.
The project can be transferred to PR200 irrespective of whether
the modules are connected or not.
When a module is added to configuration, additional inputs I1...
I8 and outputs Q1...Q8 with the module number in brackets
appear in the workspace (Fig. 5.3).
When a module is added to the project, its inputs and outputs
become available for polling.
To read the inputs or change the status of the outputs, create
variables of the appropriate type and associate them with
module I/Os. If it is necessary to sample the module I/Os over
the network, they have to be associated with network variables. Fig. 5.3

6 Firmware update
If a new project is loaded into the device and the firmware of the device and extension module are
incompatible, the connection between them will be interrupted and the red ERROR indicator on the
module will flash.
To update firmware:
1. Connect the module to the basic device over internal bus.
2. Connect the basic device to the PC.
3. Switch on the power supplies of the basic device and the module.
4. Start ALP and select the menu item Device > Firmware updater.
5. Click No in the opened dialog to select the module manually.
6. Open the tab Extension modules, select the extension number and the device model and
confirm with Select
NOTICE
Ensure reliable power supply of the basic device and modules during the update. If it
failed, the update should be probably repeated.
