period multiplier

A property of a Task that permits the Task’s execution rate to be a multiple of its
Modules period.

physical

Refers to devices at the electronic or machine level in contrast with logical. Logical
implies a higher view than the physical. Users relate to data logically by data element
name; however, the actual fields of data are physically located in sectors on a disk.

pin

Block, macro, or module parameter that creates a signal used to make
interconnections.

PLC

Programmable Logic Controller. Designed for discrete (logic) control of machinery.
It also computes math (analog) function and performs regulatory control.

product code (runtime)

Software stored in the controller’s Flash memory that interrupts the application
configuration and performs the requested activities. This includes code such as I/O
drivers and control block libraries.

put into database

Command in the Device menu used to add configuration information into a system
database.

realtime

Immediate response. It refers to process control and embedded systems, and fast
transaction processing systems that must respond instantly to changing conditions.

reboot

To restart the toolbox.

recipe

Information for process line or paper mill that provides setup data, such as speed,
length, and tension.

register page

A form of shared memory that is updated over a network. Register pages can be
created and instanced in the controller and posted to the SDB.

relay ladder diagram (RLD)

A ladder diagram has a symbolic power source. Power is considered to flow from the
left rail through a contact to the coil connected to the right.

Resources

Also known as groups. Resources are systems (devices, machines, or work stations
where work is performed) or areas where several tasks are carried out. Resource
configuration plays an important role in the CIMPLICITY system by routing alarms
to specific users and filtering the data users receive.
