Chapter 1

Introducing the E-PDISO16

Overview: E-PDISO16 features

This user's guide contains all of the information you need to connect the E-PDISO16 to your network or computer and to the external devices you want to control. You can use the E-PDISO16 in your control applications to switch on and off a variety of devices, such as fans, blowers, pumps, etc.

The E-PDISO16 is a data acquisition Ethernet interface module supported under Microsoft and Windows XP.

The E-PDISO16 provides 16 relay outputs and 16 isolated digital inputs. All I/O connections are made to three sets of screw terminals on the module.

The 16 individual, optically isolated (500 V) digital inputs can be driven by either AC (50 to 1000 Hz) or DC at levels up to 30 volts. Each input channel has a software-enabled low-pass AC filter with a time constant of 5 ms (200 Hz). The 16 inputs can be read back as a single byte.

The 16 outputs are single-pole double-throw (SPDT) dry contact, Form-C electromechanical relays. The screw terminals provide three connections to each relay – normally open (NO), normally closed (NC), and common (C). The relays are in a non-energized state (NC) upon power up.

Windows® 2000

The E-PDISO16 is powered by an external +9 V regulated power supply that is shipped with the module. A power output lets you power additional Measurement Computing products from one external power supply. Depending on your load requirement, daisy-chained modules may require a separate power supply.

On-board LEDs display the status of communication, external power, and the Ethernet connection. A fourth LED is used for testing purposes.

The E-PDISO16 is shipped in a rugged metal enclosure that you can mount on a DIN rail or on a bench.

1-1

E-PDISO16 User's Guide Introducing the E-PDISO16

Ethernet interface

The E-PDISO16 has one built-in 10/100 BASE-T auto-negotiation, high-speed communication port. With the Ethernet interface, you can remotely access and configure your E-PDISO16 from anywhere on the network. Only one computer can control the E-PDISO16 at one time. The networking protocol is TCP/IP. You can send your data over 100 meters at data speeds of up to 100 Mbps using only one Ethernet cable connected to your computer.

You configure the Ethernet connection settings with InstaCal. MCC assigns a unique physical (MAC) address to each module you connect to your network. You can restore the factory-default Ethernet connection settings with an on-board RESET button.

Max number of TCP connections to the E-PDISO16

The maximum number of TCP connections that may concurrently be connected to the E-PDISO16 is three. The first user to establish a TCP connection can change the configurations and write to the outputs. The remaining two users may access the unit on a "read-only" basis. An attempt by a fourth user to gain a connection with the E-PDISO16 will not be acknowledged. Performance of these three concurrent connections will be subject to the limitations of the network topology and the network traffic that they are connected to.

Configuration information

For more information on InstaCal and the Ethernet configuration settings for your E-PDISO16, refer to the "PDISO8 and PDISO16 Series" section of the "Digital Input/Output Boards" chapter in the Universal Library User's Guide.

Unpacking the E-PDISO16

As with any electronic device, you should take care while handling to avoid damage from static electricity. Before removing the E-PDISO16 from its packaging, ground yourself using a wrist strap or by simply touching the computer chassis or other grounded object to eliminate any stored static charge.

If your E-PDISO16 arrives already damaged, notify Measurement Computing Corporation immediately by phone, fax, or email. For international customers, contact your local distributor where you purchased the EPDISO16.

! Phone: 508-946-5100 and follow the instructions for reaching Tech Support. ! Fax: 508-946-9500 to the attention of Tech Support ! Email: techsupport@mccdaq.com

Installing the software

Refer to the Quick Start Guide for instructions on installing the software on the Measurement Computing Data Acquisition Software CD. This booklet is available in PDF at www.mccdaq.com/PDFmanuals/DAQ-Software-

Quick-Start.pdf.

Connecting the external power supply

Power to the E-PDISO16 is provided with the +9 V, 3 A external power supply (CB-PWR-9V3A). It does not matter if you connect the external power cable before or after you connect the Ethernet cable. To connect the power supply to your E-PDISO16, do the following.

Connect the +9 V DC power supply cord to the connector labeled

IN on the module). Refer to on page 3-1 for the location of this connector. Figure 3-1

Connecting the Ethernet cable

Your computer communicates with the E-PDISO16 remotely via the Ethernet cable. To connect the Ethernet cable to the E-PDISO16 and to the network, do the following:

Connect the Ethernet cable to the Ethernet communication port on the E-PDISO16.

Use a standard Ethernet CAT-5 shielded or unshielded twisted pair Ethernet cable.

Plug the cable into your network's Ethernet connection.

The

LINK LED illuminates steady green to indicate that you have established an Ethernet connection

between your E-PDISO16 and the network.

2-2

E-PDISO16 User's Guide Installing the E-PDISO16

Connecting the E-PDISO16 to your computer's Ethernet port

If your computer is not connected to a network, or if you just want to connect the E-PDISO16 directly to your computer, use a standard cross-over cable for your Ethernet connection (such as a BELKIN A3X126-07-YLWM CAT cross-over cable). Connect the cross-over cable between the unused Ethernet port on your computer and the Ethernet port on the E-PDISO16. Once connected, set up your TCP/IP address using InstaCal.

If the LINK LED is not illuminated, you cannot communicate with the network (or with the computer if you are connected directly). Refer to Chapter 5 Ethernet Troubleshooting

for possible solutions to connection problems.

Configuring the E-PDISO16

What you need to do to configure the Ethernet parameters of the E-PDISO16 will depend on whether or not you have a DHCP server enabled on the network you are connecting to. If you don’t know if the network has a DHCP server, consult your network administrator.

If your network does not have a DHCP server

If your network does not have a DHCP server, it will be necessary to set up a subnet that is compatible with the default settings of the E-PDISO16. If you are not familiar with TCP/IP configuration, consult your network administrator. Once you have set up your network to be compatible with the default settings of the E-PDISO16, connect one E-PDISO16 to the network. The next step is to assign a unique IP address to this module. To do this, proceed to the Run InstaCal section below. You’ll need to assign a unique IP address to each E-PDISO16 you want to connect to your network.

If configuring a second device, you may need to delete the arp entry on your PC for the first device. The default IP address will be associated with the MAC address of the first device you configured. The second device will have the same default IP address, but a different MAC address. Because of this, the device at the default IP address may be reported as “unreachable”. To resolve this conflict, refer to Chapter 5 Deleting an ARP table

entry.

If your network does have a DHCP server

If your network has a DHCP server, the E-PDISO16 should be assigned an IP address shortly after being powered up and attached to the network. Proceed to the Run InstaCal section below. InstaCal will display the ethernet settings assigned to the E-PDISO16.

Run InstaCal

After connecting the external power and the Ethernet cable to the E-PDISO16 module, run the InstaCal software and add the module to InstaCal's configuration file. Refer to the Quick Start Guide that shipped with the module for instructions.

After adding the E-PDISO16 to InstaCal's configuration file, configure your Ethernet connection and AC filter settings with InstaCal. If your network does not have a DHCP server, disable DHCP on the E-PDISO16.

Dynamic Host Configuration Protocol (DHCP)

Dynamic Host Configuration Protocol (DHCP) is a service that automatically assigns IP addresses to clients supporting the protocol. The default DHCP setting for the E-PDISO16 is Enabled.

A DHCP-based device does not have a permanently assigned IP address. When you power-up or reboot the computer, the DHCP client requests an IP address from the DHCP server. The DHCP server assigns and keeps track of all IP addresses for that sub-net.

2-3

E-PDISO16 User's Guide Installing the E-PDISO16

When a DHCP device requests an IP address, the DHCP server assigns, or "leases", a unique IP address to the requesting device. The assigned IP address remains assigned to that device for a specified period, called the lease duration. At the end of the lease duration, the lease is either renewed or the IP address becomes available for assignment to another client.

If the DHCP client assigned to an IP address either reboots or powers down and up again, the client requests another IP address from the DHCP server, and the DHCP server assigns an IP address as before. There is no guarantee that the IP address is the same address previously assigned.

DHCP is a practical and efficient way of assigning and keeping track of IP addresses. If two clients are assigned the same IP address, a communication failure will result that affects both devices.

If DHCP is disabled

If DHCP is not enabled, enter a static IP address into your E-PDISO16. The default DHCP setting is Enabled. Unless you have a reason to disable DHCP (such as your network server is not DHCP-enabled), we recommend that you leave DHCP enabled.

If you are not familiar with networks and their configurations, consult your network administrator prior to installing the E-PDISO16. They can tell you if your network has a DHCP server, and if not, what static IP address to use.

Caution! Assigning an arbitrary IP address could result in duplicate IP addresses on the network. This

condition can cause a communication failure that affects both devices.

Detecting a duplicate IP address

The E-PDISO16 can detect a duplicate IP address on the network. If the E-PDISO16 detects a duplicate IP address, its TEST LED will flash continuously.

The only way to return the module to a stable state is to press the factory default button. This will reset the module to the factory default configuration.

IP address

An Internet Protocol (IP) address is a unique 32-bit address that identifies a device on a TCP/IP network. An IP address can be set dynamically (by a DHCP-enabled server), or you can enter a "static" address. The address is typically represented in dotted decimal notation, which is defined as four groups of decimal numbers separated by periods. The numbers can be between 0 and 255, inclusive. The default IP address is 10.0.2.251.

Subnet mask

A subnet mask is a code that helps a network device determine how a network's subnet is structured. The code is represented in dotted decimal notation. The default subnet mask is 255.255.255.252.

Gateway

A gateway is the IP address of the device that bridges subnets within a network. The gateway address is typically represented in dotted decimal notation. The default gateway address is 10.0.2.1.

Configuration information

For more information on the Ethernet configuration settings for your E-PDISO16, refer to the "PDISO8 and PDISO16 Series" section of the "Digital Input/Output Boards" chapter in the Universal Library User's Guide.

Relay output terminals (NO0 to NC15)

The E-PDISO16 provides 16 Form C electromechanical relay outputs. The Form C relay has a common (C), normally open (NO) and normally closed (NC) contact.

The screw terminals labeled screw terminals labeled

NO0 to NC7 connect to the NO, C, and NC contacts for relays 0 through 7. The

NO8 to NC15 connect to the NO, C, and NC contacts for relays 8 through 15.

Form C relay output

A schematic for Form C relay contacts is shown in . Figure 3-2

Figure 3-2. Form C relay contacts

Two 4.7 k pull-down resistor networks on the E-PDISO16 control the power-up state of each relay bank. At power-up, the relays are put into a non-energized state (NC in contact to Common).

Relay contact protection circuit for inductive loads

If you are using the relays to control inductive loads, place a diode across the load terminals to suppress the kickback voltage. If the diode is not present, the kickback voltage could cause the on-board processor to enter an unstable state. To return the processor to a stable state, unplug the power cable from the E-PDISO16 and then reconnect.

A contact protection circuit is shown in . For AC loads, install a metal oxide varistor (MOV). Figure 3-3

Power limitations using multiple E-PDISO16 modules

The maximum output current of the supplied CB-PWR-9V3A power supply is 3 A. When running at full load (all relays on and the Ethernet is active), the E-PDISO16 draws 1.7 A from the supply. If you daisy chain additional Measurement Computing products to the E-PDISO16, make sure you provide adequate power to each module that you connect.

A drop in voltage occurs with each module connected in a daisy chain system. The voltage drop between the external power supply and the daisy chain output is 0.5 V max. Factor in this voltage drop when you configure a daisy chain system to ensure that at least 6.0 VDC is provided to the last module in the chain.

Ethernet Troubleshooting

There are typically only two reasons when you cannot attach and communicate with your E-PDISO16. These are:

! The E-PDISO16 is configured incorrectly, or is operating incorrectly. ! Your network is configured incorrectly. Though the E-PDISO16 is functioning normally, you are

unable to communicate with it.

Though a detailed treatment of debugging your network is beyond the scope of this manual, there are a few things you can try to determine if the problem you are experiencing is a problem with the board or with your network configuration. If you are unable to communicate with the E-PDISO16, perform this troubleshooting procedure to try and identify the problem:

Check to see if the external power is supplied to the E-PDISO16.

If the POWER LED is off, check the power cable and the socket that the cable is plugged into.

If the cable is good, plugged in, and the power to the socket is on, then the E-PDISO16 is not powering

up correctly. Contact MCC technical support. Refer to Getting help information.

Check to see if the between the E-PDISO16 and the server/hub/switch it is connected to. If the LINK LED is off, check the following:

Check the Ethernet cable — verify that the Ethernet cable is the correct type, is not damaged, and that it is connected correctly between the E-PDISO16 and a known functional server/hub/switch (or connected to your computer if you are connected directly).

If the Ethernet cable is plugged into a wall socket, check with your Network Administrator that the wall socket is active and that it is connected to an active server/hub/switch.

If you are properly connected to an active server/hub/switch and the LINK LED is still off, there is a problem with the E-PDISO16. Contact MCC technical support. Refer to Getting help contact information.

If your E-PDISO16 is connected to a network, check to see if the ACTIVITY LED is an indication of transmitted and received data to and from the network. If the LED is solid green or not flashing at all, check the following:

If the ACTIVITY LED is solid green, your network’s traffic is at its maximum limit and no communication is possible. Check with your network administrator.

E-PDISO16 User's Guide Ethernet Troubleshooting

4. o If your E-PDISO16 is connected directly to a computer via a cross-over cable or a single hub/switch, check

to see if the

ACTIVITY LED flashes when you try to communicate with the module. The ACTIVITY LED

flashes if there is any traffic coming from the computer. If it is not flashing at all, there are two possibilities:

There is an issue with the TCP/IP settings that is keeping your computer from transmitting. Verify that your TCP/IP settings are correct, and that you are using a valid IP address for both your computer and E-PDISO16. A simple way to do this is to open a DOS Command Prompt window from your computer. Run the DOS prompt from Start►Programs►Accessories►Command Prompt. When the DOS window opens, type in "IPCONFIG" and press the

Return key.

Your computer should return a message similar to the message shown here.

If the IP Address or Subnet Mask information are all 0’s, or if the first three numbers in either the IP address or IP Mask do not match the settings set in the E-PDISO16, then the computer will not be able to communicate with the E-PDISO16. If you are unfamiliar with how to set these parameters on your computer, check with your network administrator.

o The E-PDISO16 is not receiving. Contact MCC technical support. Refer to Getting help

for contact information.

5. o If the

ACTIVITY LED is flashing, do the following:

Verify that your TCP/IP settings are correct, and that you are using a valid IP address for both your computer and E-PDISO16. A simple way to do this is to open a DOS Command Prompt window from your computer. Run the DOS prompt from Start►Programs►Accessories►Command Prompt. When the DOS window opens, type in "IPCONFIG" and press the Return key.

Your computer should return a message similar to the message shown here.

on page 4-3

o If the IP Address, Subnet Mask or Default Gateway information are all 0’s, or that they do not match

the settings for your network, then the computer will not be able to communicate with the E-PDISO16. If you are unfamiliar with how to set these parameters on your computer or do not know if they are correct for your network, check with your network administrator.

o Try to PING (Packet InterNet Groper) the Default Gateway with the IP Address listed. To use the

PING command, type in "PING <Default Gateway’s IP Address listed in IPCONFIG>" and press the

Return key.

A successful attempt to communicate with the Default Gateway returns this message.

If you receive either a "Request timed out" error or a "Destination host unreachable" error (shown below), then there is a problem with your computer connecting to your network. Check with your network administrator.

o If you know the IP address of the E-PDISO16, try to PING the unit. Use the same procedure listed

previously, type in "PING <E-PDISO16’s IP Address>" and press the then there are two possibilities:

There is an issue with the settings on the E-PDISO16. Press the

RESET button on the E-PDISO16 to

reset the IP configuration settings to factory default. If you are using DHCP, the module will acquire an IP address. If you are not using DHCP, enter a valid IP address and re-establish communication.

RESET button does not work, the microcontroller on the E-PDISO16 is not working. This is an

If the E-PDISO16 problem. Contact MCC technical support. Refer to Getting help information.

Deleting an ARP table entry

To clear previous entries of the default IP address from the ARP table, do the following:

Open a Command Prompt (DOS) window.

Type “arp –a” at the prompt.

You should see an entry that includes the default IP address of the E-PDISO16 (10.0.2.251). This is the entry you need to remove.

To remove the default IP entry, type “arp –d 10.0.2.251” and press enter.

You should now be able to communicate with a new device at the default IP settings.

Getting help

If you are unable to communicate with the E-PDISO16, first contact your network administrator to verify that you are using the correct TCP/IP network settings, and that your network configuration is working.

If your network administrator has verified your network configuration and settings, and you still cannot communicate with the E-PDISO16, the problem may be with the E-PDISO16. For E-PDISO16-related issues, contact Measurement Computing Corporation technical support by phone, fax, or email. For international customers, contact your local distributor where you purchased the E-PDISO16.
