"? STP" Command
The "? STP" command reads a given step in the Series 942 program space (24
steps total).
The syntax for this command is:
?<Space> STP <Space> <Step #>
The command will return the following information:
<Step#> <Space> <Step Type> <Space> Data.2 <Space> Data.3 ... Data.n
Table 7 below shows how to interpret the response syntax. Note that each
argument is an ASCII decimal number representing a specific value for each
parameter listed in the table.
A response for Step# 8 would be:
<8> <space> <1> <Space> <235> <space> <1> <space> <20> <space> <15>
<space> <1> <space> <0>
This tells you that Step# 8 is a Set Point step, SP is 235°. Step time is 1:20:15,
Ent1 is ON and Ent2 is OFF.
