There is a way to interrogate the TCP/IP configuration (IP address, subnetwork address, and default gateway) of the SNAP-UP1 family (SNAP-UP1-ADS, SNAP-UP1-M64, and SNAP-UP1-D64), Ethernet I/O (SNAP-B3000-ENET and SNAP-ENET-D64), Simple I/O (SNAP-ENET-S64), legacy controllers (SNAP-LCE) and the Ethernet add-on card M4SENET-100 for M4 (OptoControl) controllers.
This procedure allows you to interrogate the settings without erasing the device to factory defaults. This is the only method if you do not have a backup strategy for a controller or you do not know the I/O unit configuration, or you have neither knowledge of the strategy or the I/O unit configuration.
The process is described in this document:
You will also need a PC with a hardwired and unused RS232 port.
Install the latest version of PAC Manager.
In a nutshell:
- Create a cable to connect the PC to the brain or controller's serial port.
- With the power-off and the device removed, set the internal jumper to "loader" mode.
- Open PAC Manager. Select Tools and then "Install Firmware via Serial Connection". Then select "Install via RS232 Connection."
- An application named OptoFlashEnet appears.
- Set the serial port to the appropriate "COM" value.
- Select Device and then "Serial Connection."
- A dialog appears with the device's TCP/IP settings."Read TCP/IP Settings."
- Edit the settings and store these changes back to the device. Note, an IP address of "0.0.0.0" means the device does not have an IP address.
- Power down the device and close OptoFlashEnet and PAC Manager.
- Set the jumper back to "kernel" mode and reassemble the device.
