Wiring

Important notes:

♦

Strictly observe

the requirements for

RS485 network building!

♦

With DC power supply,

the polarity

does not matter.

♦

In case of 90...250 VAC/DC

power supply,

grounding the device

through terminal 2

is mandatory for covering

safety standards.

Warranty

COMECO warrants this product

to be free from defects in materials

and workmanship for 2 years. If your unit

is found to be defective within that time,

we will promptly repair or replace it.

This warranty does not cover accidental

damage, wear or tear, or consequential

or incidental loss. This warranty

does not cover any defects caused

by wrong transportation, storage, installation,

or operating (see 'Specifications').

Technical support

In the unlikely event that you encounter

a problem with your COMECO device,

please call your local dealer or contact

directly our support team.

Input signal wiring

Connect the input

with regard to its type

through the respective terminals

on the device back.

3-wire voltage transmitters must

be supplied externally!

Output wiring

Connect the outputs

with regard to their types

(see 'Specifications')

via the respective terminals.

RS485 wiring

Connect the unit

to RS485 network line

via the respective terminals.

Power supply wiring

Connect the right power

supply voltage for your device

(see 'Specifications').

Table 2

Protocol architecture

♦

The protocol is based

Value

on UART protocol with:

pt100, pt1000,

ptc1, ptc2,

r.0.1k,

t.c.b, t.c.j,

t.c.k, t.c.r,

t.c.s, t.c.t,

♦

ASCII protocol is used

u, u.0.10,

for communicating,

i.0.20, i.4.20

and the information

is exchanged in frames.

c, f

♦

Each frame consists of 1,

0, 1, 2

or 2 words separated

-199...999

by byte 32 (SPACE),

-199...999

and ends with bytes 13 (CR)

and 10 (LF). The first word

in the frame denotes

1...254

a parameter 'Symbol'

1200, 2400,

as taken from Table 2 and

4800, 9600

the second word (if needed)

0...999

is the parameter 'Value',

both spelled with only

0...999

small Latin letters, digits,

0...M

dots, and/or the '-' sign.

Device activating

♦

To respond to commands,

the device should be active.

♦

For a device to be activated,

it must receive a

command, where 'х' is

the value of the parameter

Address or the value '255' (if

device address is unknown),

and respond to it with ok..

♦

If a device does not respond

even to

the UART protocol settings,

chiefly Baud Rate value.

Baud Rate - as defined

by parameter Baud Rate;

Data bits - 8;

Parity Control - Even;

Stop bit - 1.
