6ES7972-0BA60-0XA0 bus connector

Use as high-speed input signal: The signal is available in the user program in the operand E 63,15. The signal delay time is 0.02 ms. The updating of the operand E 63,15 is performed before the start of each program cycle. In the Dual Port RAM (DPR) this signal is updated after each CS31 bus telegram. With the aid of the function block WOL this signal can be read in the Dual Port RAM (word address C000:1FEH, Bit 15). – Use for the high-speed counter: The signal is used as enable input for the high-speed counter.The user can enter symbol names of the program or signal abbreviations here. The plastic sheet can be detached for labelling.

The lithium battery 07 LE 90 can be inserted into the battery compartment in order to – backup data of user program in RAM – backup data of additionally in RAM contained information, e.g. flag statuses – backup of time and date (real-time clock).

Connection of the binary outputs 

The following illustration shows the circuit configuration of the binary outputs of the third group as an example. The three groups (see the terminal configuration in the illustration on the next page) are electrically isolated from each other. The outputs work with relays. Each four relays from one group have a common voltage supply (Common terminal). These Common terminals can be supplied from different voltage sources. Caution! If outputs are operated with dangerous contact voltages, the terminal block must be plugged in or unplugged only with their voltage switched off! In order to suppress switching sparks when switching inductive AC loads, the relay contacts are equipped with varistors. If, however, inductive DC loads are switched, one free-wheeling diode must be mounted in parallel to each of the loads for demagnetization (see also Figures 1–3 and 1–4).

The battery lifetime is 1.5 years (typ. 3 years) at 25 C. 

The battery lifetime is the time during which the device remains operable in order to backup data while the supply voltage of the central unit is switched off. As long as there is a supply voltage available, there is no more load on the battery other than its own leakage current. The following handling notes have to be observed:
Use only lithium batteries approved by ABB.
Replace the battery by a new one at the end of its life.
Never short-circuit the battery! There is danger of overheating and explosion. Avoid accidental short-circuits, therefore do not store batteries in metallic containers or boxes and do not bring it into contact with metallic surfaces.
Never try to charge the battery! Danger of overheating and explosion!
Replace the battery only with the supply voltage switched on! Otherwise you risk data being lost.
Dispose of battery environmentally consciously!
If no battery is built-in or if the battery is exhausted, the red LED ’Battery’ lights up
