3-2 Configuring PointScan/100 I/O 9-12-01 PointScan/100 User’s Manual
IO Toolkit
PointScan/100 or PointScan/200 modules are configured using the IO Toolkit software. Configuration
parameters are written over Ethernet, RS485, or RS232 (PointScan/440 module only) into permanent
memory in the module’s base. Refer to the IO Toolkit help for details.
Here are the basic steps for configuring a PointScan I/O module or PointScan/442 gateway.
1. Connect DC power to the module or gateway.
2. Connect an Ethernet cable to the module / gateway. Use a straight-through cable if you are
connecting to an Ethernet hub or switch. Use a cross-wired cable if you are connecting directly to a
PC. Make sure the LNK LED on the module/gateway is on solid (not blinking).
3. Run the IO Toolkit. You can use the Plug & Play Wizard to define the parameters for the module /
gateway. Be sure to do the following:
• Choose an IP address that is appropriate for your network. See the help file for details.
• Enter in the serial number that is printed on a label on the module / gateway.
• Choose a station (slave) number for the module / gateway that is unique from other modules /
gateways and the device you are interfacing to.
• Select the appropriate RS232 or RS485 com parameters (protocol, baud rate, etc.) to match the
device that you are interfacing to.
4. Once you’ve completed the wizard, save your project file. Go to the Device menu and choose the
appropriate communication device. Then go to the Operations menu and select Load. This should
set the IP address in the module / gateway and then load down your other parameters.
If this load fails for some reason, here are some items to check:
• Make sure the LNK LED is on solid. If it is off or blinking then a typical cause is a bad cable, an
incorrect cable, or you are plugged into the wrong port on your hub ./ switch.
• Try to “ping” the gateway. Ping is a utility that comes with your PC. Start an MSDOS prompt
and type “ping” followed by the IP address of the gateway and then hit .
For example, “ping 10.1.0.1” (do not type the quotes). If you get an “unknown command” error
then you will need to install the TCP/IP Ethernet protocol on your computer. If you get
“destination unreachable” then make sure the gateway’s IP address is valid with respect to the IP
address and subnet mask of your computer. If you get “request timeout” then check all the items
above.
Note: Information on Ethernet networking can be found in the online help system
for the IO Toolit.
5. Once you establish that you can communicate with the module / gateway form the IO Toolkit you
then should attempt to communicate with your device using your master software
(i.e. KepServer or Citect)
