21X MICROLOGGER OVERVIEW
OV-9
OV4.1 SAMPLE PROGRAM 1
The 21X has a thermistor built into the input
panel that measures the panel temperature and
provides a reference for thermocouple
temperature measurements. In this example
the 21X is programmed to read the panel
temperature every 5 seconds and send the
results directly to Final Storage.
TURN ON THE POWER SWITCH AND
PROCEED AS INDICATED

Key (ID:Data) Explanation
-- HELLO On power-up, the 21X displays "hello" while it
checks the memory.
after a few seconds delay
-- 11:111111 The result of the memory check. Each digit
represents a memory socket on the CPU board.
1's indicate good memory, 0's bad memory
(Section 1.5).
* 00:00 Select mode.
1 01:00 Enter Program Table 1.
A 01:0.0000 Advance to execution interval (seconds).
5 01:5 Key 5 second execution interval.
A 01:P00 Enter the 5 second execution interval and advance
to the first program instruction location. The 21X
prompts with a P when it is time to enter an
instruction number.
17 01:P17 Key in I/O Instruction 17, measure the panel
temperature in degrees C.
A 01:0000 Enter Instruction 17 and advance to the first
parameter.
1 01:1 Key in the Input Storage location in which to store
the measurement; location 1.
A 02:P00 Enter the location number. Note that the 21X
knows how many parameters are associated with
an instruction and will prompt for a new instruction
number when parameter entry is completed.
The 21X is now programmed to read the panel temperature every five seconds and place
the reading in Input Storage location 1. Before adding any more instructions, we will start the
program and display the measurement in Input Storage.
