2. Carry out settings on the DP master system:
”Object Properties” of the DP master > ”General” tab > ”Properties” button >
”Parameters” tab > ”Properties” button > ”Network Settings” tab > ”Options”
button
-- Activate equidistance on the DP master system
-- Set the length of the equidistant DP cycle (max. 32 ms).
-- Set ”Times Ti and To same for all Slaves” (results in synchronization of the
I/O data of the different DP slaves)
-- You can set the Ti and To times separately. Recommendation: Accept the
default settings for Ti and To.
