Comment:

A connection point fitted solely with digital channels occupies 1 connection point.

A connection point fitted with digital and analog channels occupies 2 connection points of the available 31.

The maximum number of remote analog units depends on the MASTER basic unit:

- 50 series: - a maximum of 31 remote analog input units or - a maximum of 31 remote analog output units

or - a maximum of 15 central extensible remote units (ICMK 14 ..) with analog    input/output extensions + 1 remote analog input/output unit (15 x 2 + 1 = 31)

or - a mixed digital/analog configuration within the previous limits

- 90 series: - a maximum of 12 remote analog input units or - a maximum of 12 remote analog output units or - a maximum of 12 central extensible remote units with analog extensions or - a mixed digital/analog configuration within the permissible limits 

The 40 and 50 series basic units provide an incorporated battery buffer in order to save the necessary information for the next startup should there be a power drop or cut.

The buffer battery is an usual in the trade Vanadium Lithium accumulator. It is soldered on a printed-circuit board inside the unit and qualified personnel can exchange it by themselves.

The accumulator is 100 % charged after 12 operating hours without interruption. Its lifetime is between 6 and 15 years; it depends on how often and how long the power supply of the unit is switched off.

The battery buffer time is 20 days at 25 °C. During that time data (e.g. flags) can be stored with power supply of the unit switched off.

The status word %IW 1062.15 (EW 62,15), Bit 3 gives information on the status of the battery (0 corresponds to error, 1 corresponds to OK).
