How many data points can be communicated over TCP with the IEC 60870-5-104 protocol?

? How many data points can be communicated over TCP with the IEC 60870-5-104 protocol?
! This question cannot be answered in general terms. Beckhoff integrates all IEC 60870-5 communication protocols in the PC-based control technology. Therefore, the number of possible data points depends on the system resources and the set cycle time. For the 104 protocol, an additional factor is the quality of the network. In the serial protocols, another important factor is the baud rate.
