A second pulse counter can be connected at terminal 29. The pulses entered are stored in the
holding registers 40031 (low byte) and 40032 (high byte). The associated duration on the
holding registers 40035 (low byte) and 40036 (high byte). First, the low byte counts upwards
(0 to 65535). If several pulses arrive, the counting value is formed by multiplying the low byte
with the high byte (32-bit value).
