M‑3311A Instruction Book
B–2
The communication database profile in M‑3311A
using DNP3 protocol is grouped into five object
types:
1.
Single Bit Binary Inputs (Status)
:
(object 01, variation 01) These are con‑
sidered as class 0 data.
2.
16 Bit Analog Output Block /Status
(setpoints)
: (object 40, variation 01,
variation 02/object 41, variation 01,
variation 02) Used to write and read all
setpoints and system setup.
3.
Control Relay Output Block (direct
control)
: (object 12, variation 01) Used
to write all configuration points.
4.
16 Bit Analog Inputs
: (object 30, varia‑
tion 02) Used to represent all demand
metering, target information, and control
information of the relay.
5.
16 Bit Binary Counters
: (object 20,
variation 02, variation 06) Used to
represent all counters. Can be used to
reset the counters using freeze and clear
function code.
6.
Static (class 0) Data
: (object 60, varia‑
tion 01) Used to represent all binary
inputs, demand metering, target and
control information, and counters. All
points in the M‑3311A relay are of static
type, meaning that an integrity poll will
dump all data to the querying RTU.
Communication Ports
The relay has both front and rear panel RS‑232
ports and a rear RS‑485 port. The front and rear
panel RS‑232 ports are 9‑pin (DB9S) connector
configured as DTE (Data Terminal Equipment) per
the EIA‑232D standard. Signals are defined in Table
B‑1, Communication Port Signals .
The 2‑wire RS‑485 port is assigned to the rear panel
terminal block pins 3 (–) and 4 (+).
Each communication port may be configured to
operate at any of the standard baud rates (300,
600, 1200, 2400, 4800, and 9600). The RS‑485
port shares the same baud rate with COM 2 (for
COM1 see Section 5.4, Circuit Board Switches
and Jumpers).
While the digital communication ports do include
some ESD (Electrostatic Discharge) protection
circuitry, they are excluded from passing ANSI/IEEE
C37.90.1‑1989. Beckwith Electric recommends the
use of RS‑232/485 to fiber optic converters to avoid
any question of surge‑withstand capability or ground
potential rise.
A null modem cable is also shown in Figure B‑1,
Null Modem Cable: M‑0423, if direct connection to
a PC (personal computer) is desired.
