*1: The applicable transmission speed depends on the communication function, subsystems, and connection method.
An FCS collects data from subsystems or sets data with control calculations to subsystems using the builder functions by way of serial communication modules. A communication module selects only one communication function, thus
two ports must have identical communication functions. It is not possible to select different communication function for every port. The communication functions and those transmission speeds for each communication module are as shown in the table below.
