Hello,
please help me with my problem.
My application is positioning with Basic positioner of Sinamics S110 (CU305). I use absolute positioning and send position setpoint from S7-1200, in OB30 cyclic interrupt block. Hardware configuration is S7-1214 connected with PROFINET to SINAMICS S110 and KP700 Comfort. To communicate between PLC and converter I use Free telegram 8/8 PZD and DPRD_DAT, DPWR_DAT blocks, PROFINET communication.
I made test program in which I send (different) reference to converter from cyclic interrupt block every 100ms. But I saw that references from some (for example every third cycle) cycles weren't sent. My conclusion is that communication is to slow. Same reference value lasts for ~130 ms so delay is ~30 ms.
Is there any way to speed up communication and receiving reference?
please help me with my problem.
