CHAPTER 3: CONFIGURING THE D20E FIRMWARE
D20E ETHERNET I/O MODULE INSTRUCTION MANUAL GE INFORMATION 55
Configuring points
The following sections provide details for configuring the D20E firmware with the following
point types:
• Digital input points on page 55
– Counter points on page 60
• Analog input points on page 63
• Control output points on page 69
The DAPserver Studio tool is used to configure the D20E modules. Most of the
configuration information provided in this chapter is associated with the DAPserver Studio
Settings > Provider tab.
Digital input points
The D20E-S module allows up to 64 status input connections and the D20E-C module
allows up to 16 digital inputs.
Single and double digital input
There are up to 64 status inputs that can be configured as:
• Single point status (see Table 4) or
• Double point status (see Table 5).
When a status input is configured as a double point, each point occupies two input spaces
on termination block TB2; for example, on the D20E-S, TB2-1 and TB2-67 represent DI#1
LSB state; and TB2-2 and TB2-68 represent DI#1 MSB state. When mapping the double
point into DAP server, you only map the LSB.

Table 5: Double Input States:
The D20MX Substation Controller does not support double Digital Input from the D20E IO
Module.
