The built-in clock (accuracy within 1 minute/month) can be read from the pro-
gram to show the current year, month, day, day of the week, and time. The clock
can be set from a Programming Device (such as a Programming Console) or the
time can be adjusted by rounding up or down to the nearest minute.
TIML(––) is a long-term timer that accommodates set values up to 99,990 sec-
onds (27 hours, 46 minutes, 30 seconds). When combined with the SECONDS
TO HOURS conversion instruction (HMS(––)), the long-term timer provides an
easy way to control equipment scheduling.
The PID(––) instruction can be used with an Analog I/O Unit to control analog
I/O.
Complete Communications Capabilities
A Host Link connection can be made through the PC’s RS-232C port or Periph-
eral port. A personal computer or Programmable Terminal (only for 1:1 commu-
nications) connected in Host Link mode can be used for operations such as
