MFET 243, Lab #4 page 2 of 7 In laboratory assignment #1 you created a template program which included the following alias I/O tags: Table 1 – Local Alias Tags Created in Lab 1 Field Device Base Address Alias Name Description Pushbutton 0 Local:6:I.Data.0 I_PB0 Pushbutton 0 Pushbutton 1 Local:6:I.Data.1 I_PB1 Pushbutton 1 Pushbutton 2 Local:6:I.Data.2 I_PB2_no Pushbutton 2 (N.O.) Pushbutton 2 Local:6:I.Data.3 I_PB2_nc Pushbutton 2 (N.C.) Selector Switch 0 Local:6:I.Data.4 I_SS0_Pos_A Selector Switch 0 (POS A) Selector Switch 0 Local:6:I.Data.5 I_SS0_Pos_B Selector Switch 0 (POS B) Red Pilot light Local:7:O.Data.0 O_Red_PL Red pilot light Amber Pilot light Local:7:O.Data.1 O_Amber_PL Amber pilot light Blue Pilot light Local:7:O.Data.2 O_Blue_PL Blue pilot light In laboratory assignment #2 you extended your template program to include alias I/O tags for the pushbutton RediPANEL (see Table 2). At this point your PLC template program should contain all of the tags shown in Tables 1 and 2.
