Creating A Configuration List; Setting The Bus Coupler Parameters; Bus Coupler Diagnostic Data - Emerson AVENTICS EtherCAT Mode D'emploi

M1 slots further divide the M1 valve module. The numbering of the M1 slots be-
gins to the right side of the bus coupler (AES-D-BC-ECAT). Bridge cards are not
taken into account. Pressure regulators occupy one M1 slot (M1 slot 5). Supply
boards and UA-OFF boards occupy one M1 slot (M1 slot 7).

Example
See g Fig. 7.
It shows a valve system with the following characteristics:
• Bus coupler
• Section 1 (S1) with 9 valves
– Valve driver board, 4x
– Valve driver board, 2x
– Valve driver board, 3x
• Section 2 (S2) with 8 valves
– Valve driver board, 4x
– Pressure regulator
– Valve driver board, 4x
• Section 3 (S3) with 7 valves
– Supply board
– Valve driver board, 4x
– Valve driver board, 3x
• Input module
• Input module
• Output module
The PLC configuration key for the entire unit is thus:

5.4.2 Creating a configuration list

The configuration described in this section refers to the following ex-
ample: see g Fig. 7.
In your PLC configuration software, open the window that displays the config-
u
uration and the window that contains the modules.
Both windows can be found in the "Slots" tab in the "TwinCAT" program (2).
In "TwinCAT", the term "slots" corresponds with modules and should
not be confused with M1 slots.

In the "Slots" tab (2), the window to the right lists all available modules. The des-
ignation used in the PLC configuration key is stated in parentheses after the mod-
ule designations.
Only one module (M1) can be added on the valve side. A "4 byte valve unit
(0x1D)" is automatically added in the default setting if the payload data length of
the valve side is maximum 4 bytes. Otherwise a "32 byte valve unit (0x7F)" is
added.
If you do not connect any valves, you must add the "valve blanking plate".
1. Select the terminal to which the desired module should be added in the left
window of the "Slots" tab (2).
2. In the right window of the "Slots" tab, use your mouse to select modules (1)
and add them to the left window in the correct sequence using the arrow but-
ton (2).

1 Selected module
The tree view on the left side displays the logical sequence of the mod-
ules while the "Slot" window displays their physical arrangement.
When you add analog modules, TwinCAT therefore always inserts
them before the digital modules in the tree view, but with the correct
module number. This sequence can vary from the sequence shown in
the "Slot" window. To check whether the configuration is correct, you
must compare the CoE objects 0xF030 (Configured Module List) and
0xF050 (Detected Module List).
3. Use the standard system manager procedure to assign the desired output ad-
dress to the valve drivers and output modules and the desired input address
to the input modules.

5.5 Setting the bus coupler parameters

The bus coupler does not require any parameters.

5.6 Bus coupler diagnostic data

Device-specific diagnostic data are displayed in the status PDO 0x1AFF (CoE ob-
ject 0xF100).
