Embodiment Construction

[0032] initial turn figure 1, the exemplary industrial control network includes a pair of industrial controllers 10 . As shown, the industrial controller 10 is modular and may consist of many different modules that are connected together in a rack or mounted to rails. Additional modules may be added or existing modules may be removed, and industrial controller 10 may be reconfigured to accommodate the new configuration. Alternatively, industrial controller 10 may have a predetermined and fixed configuration. Each illustrated industrial controller 10 includes a power module 12 , a processor module 14 and a network module 16 . Each industrial controller 10 is further shown with two additional modules 18, which may be selected according to application needs and may be, for example, analog or digital input or output modules.

[0033] One or more operator interfaces 20 may be connected to an industrial control network. Each operator interface 20 may include a processing device ...

Abstract

The invention discloses an output module which is used for an industrial controller and can be configured to simplify setting and production. The output module comprises a configurable PWM output; the output module can be scheduled to start at different time in PWM time bucket; the output module can be configured to generate a fixed number of PWM pulses; and the output module has extensible PWM time bucket. Each output terminals can be configured to go into a first state when failure is generated and can be further configured to go into a second state after the delay of configurable time, which is after the generation of the failure. The output terminal can directly receive input signals from another module and set output signals at the terminals in response to the input signals.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to the following US provisional applications: 61 / 474,027, 61 / 474,042, 61 / 474,054, 61 / 474,073, all filed on April 11, 2011. The entire contents of each provisional application are hereby incorporated by reference. technical field [0003] The subject matter disclosed herein relates generally to industrial control networks for controlling machines and industrial processes, and more particularly to receiving data from other nodes in the network and providing signals to control actuators or other devices on machines or processes output module. Background technique [0004] Industrial controllers are special-purpose computers used to control factory automation, etc. Industrial controllers typically execute control programs that are highly customized for specific control applications. Special control languages ​​such as "relay ladder logic" are often used for programming convenience device...
