Command Set

This section describes the supported two-letter ASCII commands used to configure and
operate the SMC100CC/PP. The general command format is:
Command format:
nn — Optional or required controller address.
AA — Command name.
xx — Optional or required value or "?" to query current value.
Since multiple SMC100CC/PP may be chained through the internal RS-485 Bus, each
controller uses a predetermined address (nn), and by decoding the address field of the
incoming commands, it can determine if the command is intended for it. Some
command though, can be passed without a controller address. In that case the command
applies to all concerned controllers. For example: ST0 stops the motion on all
controllers, 1ST0 stops the motion only on controller #1.
Most commands can be used to set a value (in that case the command name is followed
by the value "xx") or to query the current value (in that case the command name is
followed by a "?"). When querying a value, the controller responds with the command
it received followed by the queried value. For example, a 1VA10 sets the velocity of the
controller #1 to 10 units/second. A 1VA? sends the response 1VA10.
Not every command can be executed in all states of the SMC100CC/PP and some
commands have different meaning in different states. It is therefore important to
understand the state diagram of the controller, see section 6.1.
