PHYSICAL EXPANSION MODE

In large systems or systems which

have current absorption greater than

the limit of 1200 mA supplied by the

power supply E46ADCN or 600 mA

supplied by the E49 compact power

supply, split the system into several

sections connected to each other

using the F422 interface configured

in “physical expansion” mode. It

is important to remember that

each line must be powered by its

own power supply. To produce the

“physical expansion” mode interface

item F422 must be congured by

inserting numeric congurator 1 in

the MOD position. Positions I3 and I4

of the interface must be congured

as a function of the two modes of

use of the interface itself as indicated

below:

 If a bus system with only

temperature control devices must

be extended, positions I3 and I4 of

the interface must be congured

with addresses I3 = 1 – 9 and I4 =

1 – 9 completely independent from

the Temperature control device

addresses;

 If a bus system with Automation

and temperature control devices

must be extended, positions I3

and I4 must be congured as a

function of the conguration of

the Automation devices in the two

connected systems. Referring to

the illustration, let us suppose that

I3 = 3, I4 = 2:

 on the input bus (IN) the

Automation device addresses must

be between A = 1 / PL = 1 and A =

3 / PL = 1;

 on the output bus (OUT) the

addresses must be between A = 3 /

PL = 3 and A = 9 / PL = 9 or the

address of the next interface. It

should be stressed that all the

temperature control devices on the

system section must be congured

totally independently of the

Automation device conguration.

In any case no automation device

must be congured with the same

address (A, PL) as interface F422

(I3, I4).
