"? 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>

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.
