When using the Microvision Plus with the dedicated PROFIBUS option, the following<br />
protocols can be used, P&B Std., MODBUS RTU, P&B Inv. and P&B DP.<br />
When using all but the P&B DP option, the protocol should be implemented in<br />
accordance with the protocol specifications.<br />
However, if the P&B DP option is chosen then the communication is handled in the<br />
following way.<br />
Data is automatically configured and transmitted by the Microvision Plus to the<br />
PROFIBUS master without the need for the PROFIBUS master to send requests to the<br />
Microvision Plus, as is the case when using any of the other protocol options. The<br />
amount of data returned by the Microvision Plus is determined by the number of<br />
fastscan words chosen. Only one byte is used for the command outputs to the<br />
Microvision Plus.<br />
When using the P&B DP protocol option then one of the following should be chosen<br />
from the GSD file module list: -<br />
8 Bytes In + 1 Byte Out (choose this option if fastscan words is set to 4)<br />
12 Bytes In + 1 Byte Out (choose this option if fastscan words is set to 6)<br />
16 Bytes In + 1 Byte Out (choose this option if fastscan words is set to 8)<br />
P&B DP Input Structure<br />
First Byte<br />
Second Byte<br />
Third & Fourth Bytes<br />
Fifth & Sixth Bytes<br />
Seventh & Eighth Bytes<br />
= MVP Logic Status<br />
= MVP Thermal Capacity<br />
= MVP FS1<br />
= MVP FS2<br />
= MVP FS3<br />
If 6 fast scan words chosen then the additional bytes are included.<br />
Ninth & Tenth Bytes<br />
Eleventh & Twelfth Bytes<br />
= MVP FS4<br />
= MVP FS5<br />
If 8 fast scan words chosen then the additional bytes are included.<br />
Thirteenth & Fourteenth Bytes<br />
Fifteenth & Sixteenth Bytes<br />
= MVP FS6<br />
= MVP FS7<br />
P&B DP Output Command Structure<br />
START A = 80 Hex<br />
STARTB = 81 Hex<br />
STOP = 82 Hex<br />
RESET = 84 Hex<br />
SERIAL INHIBIT = C0 Hex<br />
CLEAR INHIBIT = 80 Hex + any of the other command options START B, STOP or RESET<br />
Care should be taken when using the CLEAR INHIBIT command as it is possible to both<br />
clear the inhibit and either START, STOP, or RESET the drive at the same time.<br />
