Command: Set Discrete Output (60)

Supported Axes:

All

See the Commands Overview topic for basic command information and how to issue commands from PLCs, HMIs, etc.

Command Parameters

#	Parameter Description	Range
1	I/O Point	any valid discrete output

Description

This command turns on the specified discrete output. To use this command, you must have defined a discrete I/O point to be an output using the Discrete I/O Configuration dialog.

For details on settings multiple outputs simultaneously, see the Using Discrete I/O topic.

This command is an immediate command. There is no limit to the number of immediate commands in a single step of a user program. Each step in a user program can have a maximum of one non-immediate command per axis.

I/O Point

When issuing this command from RMCTools, the I/O Point is the tag name of the discrete output, if it has a name, otherwise, the I/O Point will be the address of the discrete output.

Use the Discrete I/O Monitor to find the address or tag name of a particular I/O point, or to assign a tag name to an I/O point. The address number appears in the icon of each discrete I/O point in the I/O monitor.

I/O Point from a Host Controller

When issuing this command from a host controller, such as a PLC or HMI, the I/O Point must be specified in integer format. The table below describes how to determine the integer value of a discrete output.

RMC75

RMC150/RMC200

Integer Number of a Discrete Output

Integer Number = address number

The Discrete I/O Monitor also displays the integer number of each I/O point.

Examples

The integer number for output %QX2 is 2.

The integer number for output %QX13 is 13.

Integer Number of a Discrete Output

Integer Number = (32 x slot#) + I/O#

The slot numbering starts with 0 for the left-most module in the RMC150 and RMC200.

The Discrete I/O Monitor also displays the slot number and I/O number of each I/O point. For example, the I/O point 4 in slot 3 is displayed as 3.4.

Examples

The integer number for output 7 in slot 0 is:

(32 x 0) + 7 = 7

The integer number for output 1 in slot 1 (the CPU slot) is:

(32 x 1) + 1 = 33

The integer number for output 3 in slot 5 is:

(32 x 5) + 3 = 163
