SIMATIC backplane bus supply voltage 5 V DC
Max. 100 mA
Pin assignment See section Electrical connections of the AS-i master CM
1243-2 (Page 819)
Conductor cross-section 0.2 mm2 (AWG 24) ... 3.3 mm2 (AWG 12)
ASI connector tightening torque 0.56 Nm
The AS-i master CM 1243-2 is supplied over the communications bus of the . This
means that a diagnostics message can still be sent to the follog failure of the
AS-i supply voltage. The connection to the communications bus is on the right-hand side of
the AS-i master CM 1243-2.
The removable terminal for connecting the AS-i cable is located behind the lower cover on
the front of the AS-i master CM 1243-2The current carrying capacity of the connection contacts is max. 8 A. If this value is
exceeded on the AS-i cable, the AS-i master CM 1243-2 must not be "looped in" to the ASi
cable, but must instead be connected via a spur line (only one connection pair assigned
on the AS-i master CM 1243-2).
You will find additional information on connecting the AS-i cable in the section "Installation,
connection and commissioning of the modules" in the manual "AS-i Master CM 1243-2 and
AS-i data decoupling unit DCM 1271 for SIMATIC ".

Wait time 0 to 65535 m Connect "TA" and TB" as shown to terminate the network. (Terminate only the end
devices on the RS485 network.)
② Use shielded twisted pair cable and connect the cable shield to ground.
You terminate only the two ends of the RS485 network. The devices in between the two end
devices are not terminated or biased. See the System Manual section on "Biasing
and terminating an RS485 network connector"
