EM3560 BACNET ENERGY METER
Schneider Electric
11
EM3560 – Native BACnet MS/TP
Has measurement capability comparable to
EM3550 (with logging added)
Key Differentiators from other BACnet meters:
● Native BACnet MS/TP protocol
● 115.2 kbaud serial communications
● Pulse Inputs for other Energy sensors
● Native Trend_Log objects (data logging)
● Local LCD Display & User Interface
What customer benefits do these provide?

Native BACnet MS/TP protocol
• Native - built into the meter – does not require a separate
gateway and power supply
• BACnet MS/TP – as compared to BACnet IP – most
meters that support BACnet only support BACnet IP
● Most customers WANT BACnet MS/TP rather than BACnet IP
– Adding a device with BACnet IP requires a separate network drop
on a particular subnet and a dedicated IP address – the installer
must request these from the customer’s IT group
– Adding a device with BACnet MS/TP can be done easily by the
installer using a shielded twisted pair that they can run themselves
● To get BACnet IP support, simply add a BACnet router to one or
more EM3560 Meters

115.2 kbaud Serial Comm
● A commonly requested feature on other BACnet
products is faster baud rate support
● A serial (MS/TP) link with multiple devices can only
operate as fast as the slowest device
● Many BACnet system builders prefer to operate
their serial links at 76.8 kbaud
● The EM3560 supports this and also adds 115.2
kbaud

Pulse Inputs for other Energy
sensors
● The Modbus protocol is heavily used by Energy Management systems.
● Pulse outputs on Modbus EM355x models let BAS/BMS systems access
Energy Consumption while the Energy Management system utilizes the
full data set of a meter.
● Since BACnet is primarily used by BAS/BMS systems, the need for
additional output is not common.
● BAS/BMS systems that monitor energy consumption want to see all
forms energy consumption
● Electrical
● Natural Gas
● Hot Water
● Chilled Water
● Steam
● The EM3560 provides 2 pulse inputs with accumulators (energy
counters) that can be connected to simple flow sensors with pulse
outputs, and make their accumulated energy readings available via
BACnet.

Native Data Logging
●Some system designs specify local storage of measurement history
on device
●Can be recovered later if local controller or communication link fails
●Customers can always set up external Trend Logs on local
controllers, but they only store when the local controllers and
communication link are operating
●EM3560 has three native Trend log objects
● Each stores up to 5760 time-stamped records (60 days at 15 min intervals)
● Log interval is tied internally to demand interval
● Each object can be pointed to any of the 52 Data values
● Timestamps do rely on our real-time clock, which does not have a battery
backup
●Software must generate a BACnet Time_Synchronization event when EM3560 power is
restored
●An alarm bit (Binary_Object) is provided to indicate if this is needed
Schneider Electric

LCD Display & User Interface
●Simplifies setup & commissioning
●Enter or view the Device ID directly
●Set up Comm parameters
●Many MS/TP products require a PC, special cables,
custom software, etc.
