Programmable controller program optimizations for the PCS 900/ 920/ 950:
Generally, the same principles are valid as for the PCS 090 but the command
words are arranged differently. Consider especially however, the transfer of clock
time and message words.
Disable all functions not required in the command words via the programmable
controller program. Thereby, the transfer overhead of the data that are always
transferred, is reduced.
 In addition, with data word 37 command word B, you can limit the number of
message words with the bits 0..7.
If for instance you require less than 128 messages, it suffices to read a message
block of 8 words. This can be adjusted by writing xxxxxxxx 00000001 to DW37.
Depending on need, this setting of the programmable controller can be changed
(dynamically) at any time.
 By setting bit 4 of DW36 to a logical 0 in you block the reading (transfer) of the
entire LED STATUS WORDS W20..27.
 By setting bit 7 of DW36 to a logical 0 you block the reading of the command
words C, D and E.
 By setting bit 5 of DW36 to a logical 0 you block the transfer of the clock. This is
especially important since the clock is transferred each second, and thus greatly
burdens the communication. Therefore, enable the clock transfer only if you
absolutely need it.
 By setting bit 6 of DW36 to a logical 0 you block the transfer of the date. This
has only a slight meaning since the date is transferred only at changes.
Therefore, once a day.
 Avoid frequent changing of the display text, since the status words 6 to 9 are
transferred at changes.
 You can dynamically change the amount of transferred data with your pro-
grammable controller program.
If for instance, you want to realize a jog operation, go ahead as follows: disable
all functions as described above. Select jog operation text without variables.
After termination of the jog operation, the transfer functions are enabled again.
 To relieve your programmable controller program, you can use (with the PCS
950) the soft key functions for switching idle texts, menus, etc.. You can always
disable this option by redefining the soft key bar using the programmable
controller program.

Programmable controller program optimizations with the PCS maxi 9000/ 9100:
Generally, the same principles are valid as for the PCS 090 but the command
words are arranged differently. Consider especially however, the transfer of clock
time.
Disable all functions not required in the command words via the programmable
controller program. Thereby, the transfer overhead of the data that are always
transferred, is reduced.
 In addition, with data word 13 - transfer interlock - you can disable the following
transfers:
Clock time, date, messages, menus, LEDs and operating printer pages.
