Overview:

Opto22 SNAP Ethernet I/O is an Input/Output connection module. Using Opto22 SNAP Ethernet I/O systems, you can connect a wide variety of electronic and mechanical devices, such as lights, temperature and pressure sensors, motors, serial devices, and more to computers using Ethernet networks, wireless LAN networks, and even the Internet.

Note: This version of MRC Opto22 SNAP Ethernet IO only supports Digital Input modules and Digital Output modules.

Opto22 SNAP digital I/O modules handle devices that can be in only one of two states: either on or off (true or false, 0 or 1, running or stopped, etc.). Push buttons and LEDs are examples of digital devices. SNAP digital input modules send data from the device to the computer, translating signals from the device into a form computers can understand, while maintaining a protective barrier between the computer and the dangerous high voltages or other hazards of the real world.

Opto22 SNAP is no longer managed by MXM Opto22 SNAP Ethernet IO as it was in previous version of Medialon Manager. Opto22 SNAP digital I/O modules, Real or “Virtual”, Resources in your project will be accessed by the MXM Medialon IO

Installation:

Opto22 SNAP Ethernet I/O must be configured in term of IO modules and IP settings. Opto22 ioManager software is used for this purpose (IP settings & IO declarations). See the Opto 22 SNAP Ethernet IO documentation for more informations on their web site: www.opto22.com

Setup (Resource):

Resource Scanning

If Opto22 SNAP Ethernet Modules are present on the network, you can use Medialon Products Scan feature to discover them. Select the Resources node in the Medialon Products Browser. Right-click and use the New Resource Menu to start the scan process. For more information about the scan process, please refer to the Medialon Control System Reference Manual.

Setup

Medialon Products can manage Opto22 SNAP digital I/O modules as Input/Output resources.

Select I/O Ports node to display Opto22 SNAP resources:

To add a new module, select New Resource Menu:

Configure the Unit IP address of the Opto22 SNAP Ethernet brain:

Local Address defines the local IP address set to the ethernet adapter on which the SNAP Ethernet Brain is connected.

Select a digital output or input module and click on the rack position to assign a module:

Or select a HD output or input module and click on the rack position to assign a HD module:

Note: You cannot use Digital SD and HD modules on the same SNAP Ethernet Brain.

Support(Difference with previous versions):

V 1.0.6:

  • Changed: Listening UDP Port is now 5001 (was 2001).

V 1.0.7:

  • Changed: Listening UDP Port is reverted back to 2001 (was 5001 in the previous version) due to some compatibility issues.
  • Fixed: the resource status was "Opened" even if no Opto22 brain could be reached at the specified address. It is now "Opening" in that case.
  • Fixed: a resource cannot be opened sometimes when Opto22 brains are not present on the LAN for other resources or a lot of Opto22 resources are defined in the project.
  • Fixed: a resource cannot be opened sometimes if it is disabled/enabled very quickly (i.e. fast project Stop/Run toggle).

V 1.0.8:

  • Fixed: SD Digital Input Module monitoring is not updated if there's an SD Digital Output Module with higher index.
