Transferring The Configuration To The Controller; Structure Of The Valve Driver Data - Emerson AVENTICS EtherCAT Descripción De Sistema

In "TwinCAT", the term "slots" corresponds with modules and should
not be confused with M1 slots.

1 Selected bus coupler
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 user 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 unit".
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).

valve module side
1–10 I/O module-specific diagnosis, bit position corresponds with module number
You can find a description of the diagnostic data for the valve zone in
chapters 6-7. A description of the diagnostic data for AV-EP pressure
regulators can be found in the operating instructions for AV-EP pres-
sure regulators. The diagnostic data for the I/O zone is described in the
system descriptions of the individual I/O modules.
In CoE object 0x9000, the group diagnostic bits of max. 32 modules can be read
out in bytes 1–4 and the group diagnostic bits of max. 10 I/O modules can be
read out in bytes 5–6. Internal service data is displayed in bytes 7–7E.

5.7 Transferring the configuration to the controller

Data may be transferred to the controller once the system is completely and cor-
rectly configured.
1. Make sure that the controller parameter settings are compatible with those of
the valve system.
2. Establish a connection to the controller.
3. Transfer the valve system data to the controller. The precise process depends
on the PLC configuration program. Observe the respective documentation.

6 Structure of the Valve Driver Data

6.1 Process data
Incorrect data assignment!
Danger caused by uncontrolled movement of the system.
Always set the unused bits to the value "0".
u
The valve driver board receives output data from the controller with nominal val-
ues for the position of the valve solenoid coils. The valve driver translates this
data into the voltage required to actuate the valves. The length of the output
data is eight bits. Of these, 4 bits are used with a 2x valve driver board, 6 bits with
a 3x valve driver board, and 8 bits with a 4x valve driver board.

boards:
