1-3 Introduction
PL-1746-C02/C03 Module Description
The PL-1746-C02/C03-R1 Programmable Limit Switch is designed to plug into an Allen-
Bradley SLC 500 series Programmable Logic Controller rack. It accepts an absolute
position signal from any one of the standard Electro Cam Corp. resolvers. It provides
32 outputs, along with position and speed information, via the backplane of the SLC
500.
The PL-1746-C02/C03-E1 Programmable Limit Switch is designed to plug into an Allen-
Bradley SLC 500 series Programmable Logic Controller rack. It accepts a position
signal from a 1000 count quadrature incremental encoder. It provides 32 outputs, along
with position and speed information, via the backplane of the SLC 500.
On the -C02 ALL outputs are SOURCING, on the -C03 ALL outputs are SINKING.
Of the 32 outputs, 6 are real-world, high-speed power outputs. These 6 outputs and 8
high-speed inputs are mounted on the front of the PL-1746 module.
The PL-1746-C02/C03 can be programmed through the backplane or through a stan-
dard PS-6400 Keypad/Display. The PL-1746-C02/C03 does not support real-world ana-
log outputs. However, the analog values, with offset and high RPM computations in-
cluded, are available through the backplane.
The card displays either position or RPM, depending on speed, via a local 4-digit LED
display on the front of the card. It supports up to 2 remote PS-6400 keypad/displays.
High Resolution (12 bits) from the resolver (or 4000 counts from an encoder) and
Leading/Trailing edge speed compensation, are both standard features.
PL-1746-C04 Module Description
The PL-1746-C04 is a PL-1746-C01 PL
µ
S ® Plug-In Module with the local display
and rack interface removed.
It differs from the PL-1746-C01 as follows:
• The -C04 is capable of 32 outputs total, through the backplane only.
Group inputs, first cycle enable, and output enable also will come strictly
through the backplane.
• I/O racks and solid state relays are not available with the -C04 card.
• Resolver mode is selected via dip switch S1:2 (master = ON, slave = OFF).
Power to the SLC chassis must be removed prior to setting switch.
• Registers are available through the backplane to set parameters for two
analog outputs (Analog 1 & Analog 2).
• Analog quantity refers to analog modules, and will default to 0. Attempts to
change analog quantity through the backplane will result in read only errors.
• There is no local 4-digit RPM/Position display on the front of the module.
• Attempts to change rack quantity will result in read only errors.
