Figure 4-25 Selecting a signal

6. Interconnect all signals you need.

How to transfer a signal from SIMOTION to TM31 (PROFIBUS receive direction):

1.Double-click the "PROFIBUS" entry in the "Communication" dialog of the TM31 you created. The corresponding dialog box opens.

2.Click "Binector/connector converter" in the "PROFIBUS receive direction" tab. The "Connector/binector converter" tab opens

3.Interconnect all required signals. Proceed as defined in the description of the "PROFIBUS send direction".

Creating an I/O variable in SIMOTION

Create the I/O variables in SIMOTION SCOUT in order to access the signals of TM31. You require the input or output addresses for the TM31 message frame in the "PROFIBUS Message Frame" dialog box. This allows you to assign the variable either as a complete word, a byte or a single bit.

1.In the Project Navigator, double-click "I/O" below the created D410. The symbol browser opens

2.Enter a name for the I/O variable.

3.Enter an I/O address, e.g.

PI277.0 - This accesses PSD1, bit 0 of the configured message frame. PI276.0 - This accesses PSD1, bit 8 of the configured message frame. SIMOTION can now access the signal.

The PROFIdrive profile specifies that the process status data (PSD) is defined as a 16-bit value. Take into account when determining the I/O address that the least significant byte of the SIMOTION I/O variable is assigned to the most significant PSD bits of the message frame and vice versa:

I/O address				Byte 276								Byte 277
Bytes represented in	7	6	5	4	3	2	1	0	7	6	5	4	3	2	1	0
bit format
PSD in bit	15	14	13	12	11	10	9	8	7	6	5	4	3	2	1	0
