Connecting The Power Supply And The Bus Cable; Starting The Device; Commissioning The Ma 204 On The Profibus Dp; Preparing The Control System - Leuze electronic MA 204i Technical Description

Unimpaired operation is only guaranteed when the functional earth is connected properly.
All electrical disturbances (EMC couplings) are discharged via the functional earth
connection.
3.3.3

Connecting the power supply and the bus cable

 Ideally, use the ready-made cables listed in chapter 14.5.3 to connect the gateway to the
power supply via the PWR IN connection.
 For the connection of the gateway to the fieldbus via the HOST / BUS IN connection,
the ready-made cables listed in are preferred.
 If applicable, use the BUS OUT connection if you would like to construct a network with
linear topology.

Starting the device

 Apply the supply voltage +18 ... 30 V DC (+24 V DC model).
The MA 204i
3.5 Commissioning the MA
 Complete the necessary steps for commissioning a Siemens-S7 control as described
below.
Further information regarding the individual commissioning steps is provided in see chapter
12.3 "Configuration steps for a Siemens Simatic S7 control".
3.5.1

Preparing the control system

 In the first step, prepare the control for consistent data transmission.
During programming the control system must be prepared for consistent data transmission.
This varies from control system to control system. The following possibilities are available
for the Siemens control systems.
S7
The specific function blocks SFC 14 for input data and SFC 15 for output data must be
integrated in the program. These are standard function blocks and are used to facilitate
consistent data transmission.
Notice!
If an S7 control is used, you need to ensure that Simatic-Manager Version 5.4 +
service pack 5 (V5.4+SP5) or higher is used.
