The Ethernet Remote Master modules allow you to expand the I/O count in DL205 and DL405 systems. ERMs and ERM100s are configured using the ERM Workbench, which is installed alongside NetEdit v3.17j (or later).

 How much of this remote I/O can I add to each system? Glad you asked. Here's a few facts to start with:

  • Each ERM or ERM100 can support up to 16 remote nodes.
     
  • A remote node can be an H2-EBC / H2-EBC100, an H4-EBC ( with up to 3 expansion bases), a T1H-EBC / T1H-EBC100, or a GS-EDRV / GS-EDRV100.
     
  • The remote I/O network can consist of any combination of the above nodes.
     
  • You can use any I/O modules that are currently supported by the respective EBCs and EBC100s.

3 Each ERM has an 8Kbyte buffer for the I/O. There are a few high density, analog-only configurations that cannot be addressed by the ERM. These configurations, while highly unlikely, are still possible to construct. The ERM configuration tool will alert to you any configuration problem.

Here are a two examples of maximum configurations (assuming 16 identically configured remote nodes):

H4-EBC with expansion bases:

  • If you're using 8 channel analog modules,
    each remote base can have 23 - 8 channel modules.

  • If you're using 16 channel analog modules,
    each remote base can have 13 - 16 channel modules    .

Terminator I/O - T1H-EBC:

  • If you're using 8 channel analog modules,
    each remote base can have 13 - 8 channel modules.

  • If you're using 16 channel analog modules,
    each remote base can have 7 - 16 channel modules.
Firmware

 

Upgrading the firmware in all of our ERMs is done through our free Ethernet Module Configuration utility NetEdit3. If you don't already have a copy of the utility, you can use this link to download NetEdit3 from our web site.

Once you have NetEdit3 installed on your PC, use the File->Live Update feature to download the latest version of the firmware files from the Host Engineering website. Follow the instructions in NetEdit3 to perform the actual update.
