The same port can be used to connect with PanelView 800 using the 1761-CBL-PM02 cable.
The RS232 port supports DF1, DH485, Modbus, ASCII protocols. With the attachment to any base unit, this controller is able to use the integrated RS232 port which supports communication to Human Machine Interface (HMI), Supervisory Control And Data Acquisition (SCADA), Remote Terminal Unit (RTU) devices, and programing workstations.
This memory is partitioned to user program amounting to 3.6KB and 4KB user data. The 1764-LSP features an integrated memory amounting to 7KB. The 1764-LSP was declared discontinued on. The MicroLogix 1500 controller are obsolete products therefore, this product is available as a spare part only. This controller supports a maximum of 512 Inputs and outputs, which is the ideal I/O range of small machine or process applications. This controller supports installation of up to Eight (8) local I/O modules as well as installation of expansion back where up to Sixteen (16) Compact I/O modules may be installed. The 1764-LSP is a MicroLogix 1500 Controller that is manufactured by Allen-Bradley. The MicroLogix 1500 RTC modules comes with a Lithium battery for memory retention. This processor can have the following real time clocks and memory modules installed: 1764-MM1, 1764-MM2, 1764-MM3, 1764-MM1RTC, 1764-MM2RTC, 1764-MM3RTC, 1764-RTC. The 1764-LSP can be installed with MicroLogix base units such as 1764-24AWA, 1764-24BWA, and the 1764-28BXB. These 3/4-turn analog potentiometers allow easy and quick adjustment of counters, set points, and timers. It has two built-in Trim Potentiometers with a digital output range of 0-250 volts.

The 1764-LSP Processor features one non-isolated RS-232-C port with ASCII, DF1 half-duplex, DF1 full duplex, DH-485, and Modbus protocols. Floating point data files can also be developed, each of which contains a maximum of 256 IEEE-754 floating point data elements.
Long-integer data files (32-bit signed integer, +/- 2 billion) can be created for use with embedded high-speed I/O and math instructions.
#REAL TIME CLOCK ADJUST RSLOGIX 500 SOFTWARE#
Programs are created using a Windows-based programming software RSLogix 500. The 1764-LSP MicroLogix 1500 Processor has approximately 1 ms program execution time for a 1K-word program (including counter, bit, math instructions, and timer). The processor memory also stores function files that are user-specified and are used as configuration data for system resources. These program and data file sizes are user-configurable with a maximum user data capacity of 4K words. This memory size is the total of the combined 3.65 KB User Program and 4 KB User Data. This controller has integrated 7K user program capacity. The Allen-Bradley 1764-LSP is a MicroLogix 1500 processor. Surplus and/or refurbished replacement 1764-LSP units instead of Manufacturer, however we specialize in obsolete parts and can likely still *The Allen Bradley 1764-LSP has been discontinued by the

Consult your programming guide on using the free running clock, you can download it from ab.com/manual on line.Series B 12K (8K Program 4K Data) Series C: 14K (10K Program 4K Data) For something like a motor run hour timer, the resolution issues may not be a problem. You can also use bits from the free running clock to trigger the addition of time to a floating point number, but you will miss time slices when you enable and disable the timing, but not between. Warning: Be very careful that you do not put a negative number into the timer accumulator or you will fault the processor. Adjust the resolution according to your needs.
#REAL TIME CLOCK ADJUST RSLOGIX 500 CODE#
The following mnemonic code shows a floating point long duration timer in F8:0 with a time resolution of 0.001 hours. Ive done this many times to create high resolution long duration timers. This way you won't loose any time due to scan rates. If it is, subtract that duration from the accumulator, leaving any result >= 0 in the accumulator, and add that value to a floating point number. If this matters to your application then you should not use the timers DN bit, but rather set the timer preset to 32767 and use a comparrison insturuction to see it the timer value is greater than a certian time duration. What this means is that if your scan is long enough, and your timer happens to time out in mid scan and its location in the logic is such that it is not picked up until the next scan, you can have significant cumulative error. With a 100,000 hour meter, scan rate/timer resoultion differences can add up to be significant.

If it does not, you can download a flash upgrade from ab.com that will let you upgrade the PLC firmware to support floating point math. First off you will need to make sure your version of ML1200 supports floating point math (series C OS).
