Setting the Module ID with the DIP Switch
The ECOM’s DIP switches contain eight individual slide switches, but not all of these are
active. The individual slide switches are labeled 1 through 8 on the body of the DIP switch
(upside down in the following figures).
You will find that the printed circuit board is labeled 0 (zero) through 7. We use the labeling
on the printed circuit board in describing how to set the switch. The table below shows the
meaning of each dipswitch based on the version of the module being used.
The dipswitch numbers on the printed circuit board indicate the power of 2 represented by
each slide switch. For example, switch 0 represents 2
0
(or 1), switch 1 is 2
1
(or 2), switch 2 is 2
2
(or 4), and so on. The following figures show the binary value of each switch in parentheses ( ).
You can use the DIP switch on the ECOM module to set the Module ID to a number from
1 to 63. Each module on a given network must be assigned a unique Module ID if the Module
ID is to be used for communications. Do not use Module ID “0” for communications.
If the DIP switch is set to a number greater than 0, the software tools are disabled from setting
the Module ID. The software tools will only allow changes to the Module ID if the DIP switch
setting is 0 (zero, all switches OFF). The DIP switch settings are read at powerup. You can use
the software tools to set the Name and IP Address even if you use the DIP switch for setting
the Module ID.
WARNING: Using duplicate Module IDs on a single network will cause unreliable PLC-to-PLC
communications.

RBE (Report by Exception) - Dipswitch must be ON for this function.
IBox (Intelligent Boxes) - Dipswitch must be ON for the ECxxxxx IBoxes to Function.
Recover - Dipswitch used to reset IP settings back to factory default on power-up in case device is lot on network.
Protect - Dipswitch must be ON to write protect firmware and network, node, peer-to-peer, SMTP (email) configurations.
Module ID - Bit-weighted for manual setting of this parameter.
