MODBUS RTU, also known as “MODBUS binary”. The Modbus slave address of the 115S is selected via two rotary switches on the bottom panel of the case. All 115S models provide digital inputs and outputs. Specific models provide analog inputs or analog outputs. - Page 6 Figure 1-1: 115S unit with significant parts labeled. Two ports allow configuration and communications on the 115S. The RS232 port is intended for configuration. The RS485 port allows the unit to be in a multi-drop configuration. Overvoltage protection and supply monitoring is provided to minimize the risk of failure due to faulty connections or supply surges.

Page 7: Module Types And Features
Table 1-1: Summary of 115S module types and I/O. 1.1.1 Digital inputs / outputs Each digital I/O channel on the 115S modules can act as either an input or an output. The input/output direction does not need to be user configured. -
Page 8: Pulsed Inputs
115S Serial I/O Module User Manual • The Update Time is the interval in which the 115S expects to receive updates to the Target value. The module will output enough pulses for the Count to reach the Target within the update time. The output pulse rate is determined by the update time, and the difference between the count and the target. -

The modules are fitted with a termination switch for the RS485. Set this switch only on the last module in a multi-drop RS485 configuration. The ELPRO E-Series software is used to configure the 115S modules as part of an E_Series network. The hardware set-up for items such as expected pulse rates and analog signals is also available through this software. -

Page 12: Address Switches
The address switches are found on the bottom panel of the module, as shown in Figure 2-3. If you are using the 115S module with other ELPRO E-Series modules (ELPRO 105 and 905- modules), the address switches must be set to “00”. This enables ELPRO protocol mode and assigns 3 serial addresses to each module. -
