Ethernet Addressing Basics Particle Measuring Systems instruments must be properly configured for Ethernet communications in order to work. There are multiple numeric parameters required to properly configure an instrument and a small error in one or more of these parameters can result in no communications, or worse—sporadic communications.
172.31.255.255 192.168.0.0 192.168.255.255 C (16 Bit Range) Particle Measuring Systems provides a unique default address in the Class A range for every instrument. Whenever the instrument is set to default parameters or factory defaults, this address is restored. Network Mask The network mask is used to discern the network portion of the IP address from the location portion.
For all Particle Measuring Systems instruments, this is done at least once when the instrument boots. In some newer instruments, the MAC address is announced to the switch or router every time a network connection is detected.
Chapter 3 Ethernet Communications Overview Static IP Addresses versus DHCP Addresses All Particle Measuring Systems instruments use a static IP address. This means the address is predefined. The address is used to identify the instrument when data is collected. In contrast, many computers use a dynamic IP address (i.e., DHCP or Dynamic Host Configuration Protocol).
Chapter 3 Ethernet Communications Overview 2 Verify the device can talk using PING. a. Open a command shell on a PC, and type PING aaa.bbb.ccc.ddd where aaa.bbb.ccc.ddd is the address of the device. If there is no response, then there is an addressing problem. Figure 3-2 Example for PING test b.
There are two ways to establish a direct Ethernet link between a laptop (or other PC) and a Particle Measuring Systems instrument. The first way is to modify the PC Ethernet settings to work with the existing instrument settings. The second way is to modify the instrument settings to work with the existing PC settings.
Chapter 3 Ethernet Communications Overview a.2 Right click on the adaptor, and then select Properties. A window similar to that shown in Figure 3-4 3-7 should be on page displayed Figure 3-4 Local Area Connection Properties window b. Select the item Internet Protocol (TCP/IP). If given an option for Version 4 or Version 6, select the one titled Internet Protocol Version 4.
Chapter 3 Ethernet Communications Overview Figure 3-5 Internet Protocol (TCP/IP) Properties window with IP address and subnet mask defined d. Record the existing settings on the Internet Protocol (TCP/IP) Properties window. These settings will need to be restored after the instrument communication session is complete.

Chapter 3 Ethernet Communications Overview APIPA allows a PC to automatically assign itself an IP address even when no DHCP server is present to provide an address to the PC. Translated this means that by assigning the right address to an instrument, it will talk one to one with a Windows machine without setting an address on the Windows machine.

Chapter 4 Configuring for Ethernet Configuration Basics Configuration is the process of entering Ethernet settings that will allow the MiniCapt Remote Microbial Air Sampler to communicate over a specific network. Appropriate Ethernet settings are required for the Modbus TCP protocol (see Chapter 5, “Modbus Protocol.”)for use with third party applications.
Chapter 4 Configuring for Ethernet RS-232 Cable A RJ-12 to RS-232 Serial Adapter Cable (PMS-CD1995) can be purchased from Particle Measuring Systems. The wiring for this cable is as follows: Table 4-1 RS-232 Pin Outs (RJ-12 jack) Pin 1 Pin 2 Transmit ®...
Chapter 4 Configuring for Ethernet When communications are established with the unit, a prompt appears. Enter the Configuration commands (see “Configuration Commands” below) to set the following addresses: Set the IP address. Set the Net mask. Set the gateway address. Enter the “write”...
Page 41
Chapter 4 Configuring for Ethernet Set gat(eway) aaa.bbb.ccc.ddd The gateway address is used when communicating across different networks. This command sets the gateway address in a form of aaa.bbb.ccc.ddd. Each three-digit series is a value of 0-255 separated by a period (.) character. Use gateway 000.000.000.000 if no gateway device is available on the network.
Chapter 4 Configuring for Ethernet Write Saves the most recent changes. You must send this command after setting up the instrument, or your parameters will be lost when the sensor is de-energized. NOTE: When the programming is complete, record these settings for future reference.
Chapter 4 Configuring for Ethernet Connecting the Ethernet Cable The MiniCapt Remote communicates with a third party Modbus application by means of a CAT 5 UTP Ethernet cable. The sampler is designed to work best with a CAT 5 UTP cable.
Chapter 5 Modbus Protocol Communications with the MiniCapt Remote Microbial Air Sampler are available via Modbus TCP. The instrument presents a single TCP/IP Ethernet connection at port 502 using the standard Modbus protocol. Two specification documents were used in the development of the Modbus interface: •...

Holding Registers Chapter 5 Modbus Protocol Holding Registers Like the coils, spares are in place between the “standard” registers and those that are designated as specific/optional. There are no specific/optional coils defined for the MiniCapt. If the sample setting holding registers are sent while the unit is sampling, it will ignore the new settings until the next sample set is executed.
Chapter 5 Modbus Protocol Coils Coils Like the holding registers, spares are in place between the “standard” coils and those that are designated as specific/optional. There are no specific/optional coils defined for the MiniCapt. The data collection coil will enable/disable sampling. 00/01: Read: 1=Sampling Enabled, 0=Sampling Disabled.
Coils Chapter 5 Modbus Protocol Sample Volume Mode. The sample volume control will change how the unit 00/09: controls sampling. If set, holding register 40003 will contain the sample volume to be processed multiplied by a factor of 100. If clear, holding register 40003 will contain the sample interval to be processed in seconds.
Chapter 5 Modbus Protocol Data Register Processing Data Register Processing The unit can provide real-time data or queued data or both. There is only one section of input registers assigned for data to handle this information. If the unit is setup to queue data then the data shown is the oldest data in the queue. The data available coil (00/02) will be set on a read if there is data in the queue.

Chapter 7 Maintenance and Performance Checks There are no user-serviceable items in the MiniCapt Remote Microbial Air Sampler. You can, however, clean the sampler’s housing, replace batteries, repair or replace cables and cable connectors. Cleaning the Sampler’s Housing WARNING Disconnect the power cord from its power source. The sample probe must be capped before the instrument is sterilized by means of liquid, spray, or mist.
Chapter 7 Maintenance and Performance Checks Performance Checks Performance Checks Complete the following procedures to verify that your instrument is operating properly. Airflow Rate Check The sample flow is factory-set using a critical orifice and is not adjustable. If the flow drops by 15% there may be a blockage in the critical orifice or inlet jet.
The below procedure describes the recommended practices for MiniCapt and BioCapt impactor heads and related cleaning accessories. Particle Measuring Systems assures that all delivered products and materials are tested and cleaned according to the most demanding cleanroom requirements. In addition, the presence of manufacturing and/or handling residues may occur for 316L Stainless Steel items such as MiniCapt or BioCapt impactor heads which undergo a highly complex machining process.
The above procedures are intended to provide general guidelines and may not be applicable in some specific manufacturing scenarios. For more information, contact your Particle Measuring Systems local representative or go to www.pmeasuring.com. Page 8-2...
