Data word Name Direction Type of signal

150.00 Strobe M function NC → PLC Strobe

The signal is set to "0" if the data word is valid for the "M function". It is set

to value "1" if the acknowledgement signal of the PLC has changed from "1"

to "0". After switching on the control, the signal has the value "1".

Effect in the PLC: If the signal has the value "0", the data word of the "M func-

tion" is accepted. The acknowledgement signal is set to the value "0" after

acceptance. If the strobe has value "1", the acknowledgement signal is set to

"1".

In the case of synchronized M functions, the "Read enable" signal is with-

drawn. This takes place before the acknowledgement signal is set.

Data word Name Direction Type of signal

151 M function NC → PLC Message

The data word contains the number of the M function in binary representa-

tion (0 ... 9999). The M function can be programmed in the parts program or

generated by pressing the key.

The numbers of the M functions are partially defined by standards (DIN

66025); the free numbers can be assigned application−specifically. For a list

of defined M−numbers for the ETC including description, refer to the ETC pro-

gramming NC operating system.

Effect in the PLC: Execution of the function specified via the M function. Read

enable is activated after the function has been completed or at another sui-

table point in time.

Data word Name Direction Type of signal

159.00 Strobe H function NC → PLC Strobe

The signal is set to "0" if the data word is valid for the "H function". It is set

to value "1" if the acknowledgement signal of the PLC has changed from "1"

to "0". After switching on the control, the signal has the value "1".

Effect in the PLC: If the signal has the value "0", the data word of the "H func-

tion" is accepted. The acknowledgement signal is set to the value "0" after

acceptance. If the strobe has value "1", the acknowledgement signal is set to

"1".

If the data acceptance takes longer (>10 sec.), the "Read enable" signal must

be withdrawn. This must take place before

the acknowledgement signal is

set.
