PROFIBUS-DPV1
The following PROFIBUS-DPV1 functions are available on the FX5-DP-M.
• To use the PROFIBUS-DPV1 functions, use DP-Slaves that support the PROFIBUS-DPV1.
For details, refer to the following.
Manuals for the DP-Slave
• Use the PROFIBUS-DPV1 functions by setting MSI (Min. slave interval) to a value larger than the bus cycle
time calculated from Pt (Polling time), Tsdi (FX5-DP-M request/response processing time
÷
transmission
speed[bps]), and Lr (Data refresh time). If MSI is smaller than a value calculated from Pt, Tsdi, and Lr,
function processing may take longer than expected. (
Acyclic communication function
This function enables reading/writing data from/to DP-Slaves at any time apart from the data exchange.
A maximum of eight requests can be issued.
Precautions
The Acyclic communication function cannot execute with the global control function.
