70 6250 Servo Controller User Guide
The RP240 is used as the 6250's operator interface, not a program entry terminal. As an
operator interface, the RP240 offers the following features:
❏ Displays text and variables
❏ 8 LEDs can be used as programmable status lights
❏ Operator data entry of variables: read data from RP240 into variables and command value
substitutions (see table in Appendix B of software guide)
Typically the user creates a program in the 6250 to control the RP240 display and RP240
LEDs. The program can read data and make variable assignments via the RP240's keypad and
function keys.
The 6000 Series software commands for the RP240 are listed below. Detailed descriptions are
provided in the 6000 Series Software Reference Guide and the Model RP240 User
