  1. GE System I/O MAIN 222 Industrial Controllers

  2. Introduction • See Unit 4 Course Manual Info • %I is an input • %Q is an output • %M is an internal bit • An internal bit is a contact or location that is memory / virtual in nature

  3. Contacts • A contact is used to monitor the state of a machine or internal reference. • Whether or not the contact passes “flow” depends on status of the reference being monitored and type of contact. Normally Open = Reference is On 1 Normally Closed = Reference is Off 0

  4. Contacts • Types of Coils • Unit 9-5 HO • Retentive • Non-retentive • Power Off then Back On Stays the Same That is Retentive • SET • RESET

  5. Types Of Contacts • %Q • Discrete machine outputs • Non-Duplicated • %M • Internal Discrete References • Not Retentive • Can be Duplicated • %T • Temporary Internal References • Not Retentive • Can be Duplicated

  6. Relay Elements • Unit 9-7 • Go over 9-8 Example

  7. Addressing Systems • Siemens • E = In • A = Out • GE • I = In • Q=Out • TI • X = In • Y = Out

  8. Write A logic Program

  9. Writing Programs Basics

  10. Where to Get More Information • See Web Site • VersaPro 2.02/3 users guide • Unit 2,4,9 from Series 90-30 Course Manual HO
