ENTEC is packaging a new Sectionalizer Control with our Load Break Switch (LBS) featuring an
SEL-751 relay, innovative smart-logic and patent pending technology. Known as LBS-751, this
new unit expands traditional sectionalizer applications and modernizes power system protection.
With three simple setpoints the factory program is push-button-ready. Let’s get started.

Port Settings
1. Open RDB with acSELerator and select OEM file saved previously in Step 4. Save-As
OEM Comm Config (e.g. Customer Field Device OEM Comm Config).
2. Use setting editor to open Port config. Make changes, save and upload new Port
settings to 751.
Quick Tip
Make sure to enable a session in either Modbus or DNP protocol when using Port 1
(Ethernet), scroll down to the bottom of Port 1 page.

Modbus Protocol Codes
02h Read Input Status (Coils) Command
Use function code 02h to read bits as individual coil values. The coil method increases data
size and may require multiple polls to completely read one device, but single binary values
placed in one coil greatly simplifies binary state determinations at the Scada master. Use
the 02h coil address provided in the status bit table above to collect data.

03h Read Holding Register Command
Use function code 03h to read holding register values containing “bit words” or analog data.
To determine data address, add 125 (decimal) to Setting location in the Modbus User-
Defined Assignment Map above.
Example 1: Phase-A Current Demand (IAD) is available using the 03h function to
read address 133 (Mod_08 Setting location + 125 = 133).
Example 2: AC Power Fail is available using the 03h function to read address 169 as
noted in the Status Bit table above. AC Power Fail can be determined from the state of bit 1
using polarity convention where Logic 1 = True Condition. The Scada master will typically
collect 16 bits (2 Bytes) from address 169. The desired bit location is determined counting
from Right to Left starting with Bit-0. The second bit counting from the right is Bit-1
representing AC Power Fail. (1 = AC Power Fail True, 0 = False).

03h command will collect all data from the LBS-751 User-Defined Assignment Map with a
single poll (125 registers). In many systems this method will collect Binary and Analog
points with a single poll allowing more devices to communicate with the Scada master.
Large Scada systems utilize 03h to collect binary words versus using 02h to retrieve single
binary bits.

Modbus Protocol Codes, continued
05h Force Single Coil Command
Use function code 05h to set and clear a coil. Remote bit coil will track the binary state
value forced with the 05h function. State value “1” will Set remote bit coil and “0” will Clear
the coil. Refer to Control Point table for coil assignments and address.
Example 1: Apply “Push Button Lock” with 05h function using Scada to force coil
address 27. Set Logic “1” for three seconds then clear to Logic “0” operates Button Lock
same as pressing PB1 directly on the front panel.
