Does anyone have information on the addressing prefix "B" utilized in DL06 units? I am currently working with a network of 4 Direct Logic DL06 units (D0-06AR) interconnected via ethernet using ECOM-100 cards. Some units feature additional modules such as analog input (F0-4AR2DA-1) and thermocouple (F0-04THM). My task involves deciphering the purpose of an existing program, but I am confused by the addressing format. The program assigns multiple addresses to each PLC, all starting with a "B" prefix followed by a decimal number (e.g. B3000.0, B3000.1, B3000.2, B3200.1, B3200.2, etc.). I have not been able to find any information on the standard use of this "B" address in the main manual or expansion module manuals. Has anyone encountered this type of addressing before? Appreciate any insights.
The B data type in PLC programming allows for addressing individual bits within a V memory location. This feature is documented separately from other memory types, such as V mem. For example, V2000 could be referred to as an "array of bits," while B2000.0 would represent the least significant bit of V2000, also known as "Bit 0 of V2000" in the description. While this explanation may seem lengthy, it effectively illustrates the concept of working with bits within PLC programming.
This idea definitely resonates with me. Appreciate it, Mike!
Differences Between Little Endian and Big Endian Encoding
In the context of DL06 PLCs, the "B" prefix is typically used to indicate a "binary" address or a bit-oriented address. This means that each bit is individually addressable for read or write operations. The number after the B prefix (e.g., 3000 or 3200 in your examples) usually signifies the memory location, while the subsequent decimal number denotes the specific bit in that memory byte location. In essence, B3000.1 would relate to the first bit of the 3000 memory byte address. I'd recommend checking any area where these addresses are used for operations involving discrete data or Boolean logic, as they're likely used for these types of functions.
Hi there! The "B" prefix typically refers to the "Binary" register in Direct Logic PLCs. Binary registers are used for various functions including storing temporary data or logic interlocking. Their usage can largely depend on the programmer's preference. The numbers following the "B" refer to the exact register and bit being addressed which can vary widely based on the needs of the particular program. Going through the program line by line should give you a fair idea about what role these addresses are playing. Hope that helps you with your project!
It sounds like you're dealing with bit-level addressing in the Direct Logic DL06 system! The "B" prefix typically indicates binary data or bits, which is common in PLC programming for things like flags or status indicators. Each address like B3000.0 corresponds to a specific bit in the word stored at that address. You might want to check if those addresses are used for specific control signals, alarms, or as part of the program logic. If the main manual doesn't provide clarity, sometimes a quick look at sample programs or user forums can shed some light on how others have structured their logic with similar setups!
It sounds like you're diving into some intricate programming! In the DL06 units, the "B" prefix usually indicates a bit-type address, often used for boolean data, such as discrete inputs or outputs. The numbers following the "B" indicate which word you’re addressing in the memory area, with the decimal notation denoting specific bits within that word. If the program is leveraging these "B" addresses extensively, it could be managing various control flags or states, so tracing those bits could offer insight into the program's operation. Have you tried looking through the project's comments or documentation? Sometimes, the previous programmer leaves clues that can clarify the logic. Good luck!
It sounds like you're dealing with bit-level addressing in the DL06 series. The "B" prefix typically indicates a bit address, which is used for binary I/O functions such as discrete data points. In the case of your addresses like B3000.0, this suggests that you're looking at a word in memory (like the data stored at D3000) where individual bits represent different inputs or outputs. If your program is using multiple bits within the same word, that’s a common practice for efficiently managing multiple discrete signals. Have you checked to see if there are any associated comments or documentation within the program that might provide context for how these bits are utilized? Sometimes developers will leave notes that can clarify their logic.
It sounds like you're dealing with some bit-level addressing in your DL06 units. The "B" prefix typically indicates that these addresses are referencing bits within a specific data register or memory area. For the DL06, "B" often points to binary outputs or flags used in your program logic. If B3000 is a memory location, B3000.0 would refer to the first bit of that memory location, B3000.1 to the second, and so on. You might want to check if those bits correspond to specific control states or statuses in your program. Sometimes, the addressing conventions can vary a bit based on how the previous programmer decided to structure things, so looking into the logic tied to those bits could provide more clarity!
