Safety Warning Refer to the Installation and Maintenance Manual, and the Operating Instructions for the particular control system before carrying out any work on PNEUDRI electronic MPXE / DXE / DHE / MXA / MPXA dryers. When handling, operating or carrying out maintenance on a dryer or associated equipment, personnel must employ safe engineering practices and observe all relevant health and safety requirements and regulations.

General The Remote Communication Package has been designed to operate on PC’s within the Windows 95/98/2000/XP, NT 3.51/4 environment, utilising a Dynamic Data Exchange (DDE) server. The use of DDE means that the data can be easily transferred to other packages supporting DDE. Upto 31 dryers can be integrated into a single system, and as with the dryers themselves the Remote Communication Package is based on a modular concept, where additional units can be added as the network grows.
Remote Communication Package Scope of Supply. The Remote Communication Package consists of the following components: - Remote Communications Enclosure containing the Active Network Interface (ANI) and local power supply. 5-metre RS232 communication cable; iii) Multi485 DDE Server installation software vii) Mating sockets for the RS485 connections on dryers.
Hardware General Arrangement The general arrangement for a 3-bank PNEUDRI remote communication installation is shown in Figure 1 below. Junction Remote Communication Enclosure Including ANI Sentinel Key 3 x 3.5” Diskettes Multi 485software Multi485.exe Program VALIDATION CODE OK Node Code Site Files Files...
Figure 2: White Control Enclosure Detail The plug is a Bulgin Buccaneer 3-pin IP68 industrial cable socket part number PX0731S. The socket should be terminated as follows: - L terminal RS485/ L1 N terminal RS485/ L2 E terminal RS485/ screen The cable can exit the dryer via an unused aperture in the black shroud support, which will require the fitting of the cable gland which is supplied.
The screen can be terminated on the controller body by crimping into a 6.3mm crimp terminal. It is suggested that only the controller end of the screen is connected to earth. 4.3. RS485 Network/Junction Box (to be supplied by customer) Depending on the dryer model and site specific conditions.
4.4. Remote Communications Enclosure The enclosure contains a local power supply, mains voltage input terminals, a 9-way connector interface and an Active Network Interface (ANI). Which are described below: 4.4.1 Power Supply The power supply provides a stable DC voltage for the ANI. The power supply requires connecting to an external fused mains supply of between 85 - 264V 50/60Hz rated at 5W.
On the ANI, there are multiple RS485 and RS232 ports. Ensure the connections are made only to the communication ports specified below. Figure 5: Active Network Interface (ANI) Terminals 4.4.3 RS 485 Connection The RS485 cable from the junction box or dryer should be fed into the Remote Communication Enclosure via an unused cable gland.
Dryer Setup. Up to 31 PNEUDRI electronic MPXE / DXE / DHE / MXA / MPXA dryers (nodes) can be connected to a single RS485 network. To remotely address each dryer, every dryer has to have a unique Machine Number. The default setting on dryers is “1”.
Software Installation Introduction To interpret the data and make it available to the widest range of programmes the software provides a gateway between the raw data provided by the dryers and then translates it and makes it available through the DDE interface supported by Windows and most Windows based packages.
Software Setup 5.4.1 Site Specific Informaion Before using the software it is necessary to finalise the site-specific settings this is most easily achieved by using “Windows Explorer” and locating the “Multi 485” directory on the hard drive. The “Multi 485” directory created is made up of a program executable <Multi485.exe>...
Using Remote Communication for the First Time On the Windows “Start/Programs” taskbar will be a title for “Multi485 DDE Server” which will lead to Multi485. If no shortcut was created the file resides inside the Multi485 directory where it can be started manually. Multi485.exe The <multi485.exe>...

i.e. ITEMFILE: DHPNDRL1V3_5.NOD becomes ITEMFILE: DHPNDRL1V3_3.NOD ITEMFILE: R1DHPNEU_V01.nod Make this change to all dryers on the network. Save this file. Returning to the "Station configuration/selection" window select "DRYER STATION" and click "Set current station" then "Save on exit" then "Exit". This will return to the main "Multi485"...

Addressing A Particular Node An individual node can be addressed through packages supporting DDE. For example, in Microsoft Excel, this is done by entering the command/request in the format shown below: =multi485|<DDENAME>!<DDE text string> Therefore, if we want to read the sizing dewpoint of dryer #1 (machine number 1) then we would enter the following: - =multi485|dryer1!GetSizingDewpoint Dryer DDE Commands...

iii) AdvDewpoint The outlet dewpoint from the dryer bank will be returned in milliCelsius. This will automatically be updated when a node status broadcast message is received. AdvPressure The inlet pressure to the dryer bank will be returned in millibar (gauge). This will automatically be updated when a node status broadcast message is received.

A “1” will be returned if the command is successfully carried out. CmdABVOnStopOn Command to configure the Automatic Bypass Valve (ABV) to open automatically when either the STOP KEY is pressed or a CmdStop is received.

xxiv) GetFaultRegister Each bit of the 4-byte (32-bit) binary number returned represents a particular type of fault event. This request therefore enables the operator to observe all ACTIVE faults without having to pole the individual Fault Registers. A “1” will be returned if that particular type of fault event is active.
