Sm@rt Dynamic Arc-Flash Sentry (DAS): Sm@rt DAS is a Sm@rt DAS system. The Sm@rt DAS system is used to control solution that allows users the ability to automatically toggle maintenance mode of VL and WL breakers in Type WL between nominal trip settings and a predefined set of lower Switchgear, SB Switchboards, P4 and P5 Panelboards.
Sm@rt DAS System Digital Inputs Introduction Each breaker that has Sm@rt DAS is assigned a digital input. It The Sm@rt DAS system consists of a controller, VL and WL moves from left to right and top to bottom in the lineup. The breakers with MODBUS communication modules, and a input requires 24V to activate.
Figure 2.4: WL MODBUS module COM21 (VL Breakers – Switchboards and Panelboards) COM16 (WL Breakers – Switchgear and Switchboards) The COM21 module connects VL breakers to the Sm@rt DAS The COM16 module connects WL breakers to the Sm@rt DAS system.
Chapter 2 Sm@rt DAS System Breaker Requirements The Sm@rt DAS system requires certain features in both the WL and VL breakers. This section highlights the requirements for breakers as well as the features for each breaker with Sm@rt DAS. Figure 2.5: WL Breakers Figure 2.6: VL Breakers...
This section will deal with the different schemes and implementations available and how they function. 24VDC Switch Inputs Power Supply (120VAC or 24VDC) Ethernet MODBUS TCP/IP Output LEDs Figure 3.1: Sm@rt DAS Controller with one switch and one light per breaker...
24VDC Single Switch Input Power Supply (120VAC or 24VDC) Ethernet MODBUS TCP/IP Output LEDs Figure 3.2: Sm@rt DAS Controller with single switch and one light per breaker...
Chapter 3 System Interfaces The HMI option is a design that replaces the switches with either a remote mount or locally mounted HMI. The HMI option allows users to turn on/off maintenance mode over the HMI vs. a switch. HMI with WL Breakers The HMI feature for the WL offers an easy way to turn on/off maintenance mode in the WL breaker on one screen.
In order to activate DAS over MODBUS, you will need a MODBUS program. Siemens has a program called Sm@rt DAS MODBUS Communication Module that can be used to read and write settings for Windows 7 and later.
Table 4.2 shows the MODBUS system codes if integration is needed to upstream devices. In order to permanently connect the Sm@rt DAS to an upstream system, the second RJ45 port of the gateway can be used. An Ethernet switch will need to be placed between the controller and gateway (Figure 4.2, 4.3) if several external...
Force single coil Table 4.1 shows MODBUS function codes used to access data Preset single register from devices. For Sm@rt DAS, Code 03 is used to read holding Write multiple registers registers and Code 16 is used to write the holding registers.
Chapter 4 Communications Siemens Sm@rt DAS Communication Module A secondary option for access to Sm@rt DAS system is using the Sm@rt DAS MODBUS module available through the Siemens Download Center. It can be used by connecting directly to the PLC or connecting through an Ethernet switch.

DAS mode (either via switch or the software) and check states on the breaker to verify the new settings. * You must read states in order to change the settings. Figure 4.6: Sm@rt DAS MODBUS Communication Module Steps...
MODBUS Register Map Each breaker has a unique section of the register map. There are 15 registers for Sm@rt DAS per breaker. The next breaker register addresses are +15 up from the current breaker. The first breaker at the leftmost and top most point of the lineup will be the first breaker.
Connecting to the breakers the MODBUS RS-485 to TCP/IP gateway. The Sm@rt DAS One key benefit of Sm@rt DAS is it allows for direct access to system uses the same IP address structure for each Sm@rt the breaker if the user wishes to make changes to trip unit DAS order unless otherwise specified.
