GE VMIVME-3128 Gas turbine counting card

The complete configuration block for the block transfer write to the module is defined in Table 4.A below.Bit/word descriptions of BTW file words are presented in Table 4.B. Enter data into the BTW instruction after entering the instruction into your ladder diagram program.These bits control the reset function. When one of these bits transitions from 0 to 1, the counter is reset to 0 and begins counting. The bits correspond to the 4 counters: bit 00 = counter 0; bit 01 = counter 1; bit 02 = counter 2; bit 03 = counter 3. bits 0407 New data acknowledge bits. When one of these bits transitions from 0 to 1 the corresponding new data bit in BTR word 1, bits 47 will be reset. Bit 04 corresponds to counter 0, bit 05 to counter 1, etc.

These bits control the preset function. 

When one of these bits is set to 1, the preset count value is automatically loaded into the counter and the counter begins counting. (Note: The preset count values are loaded into words 13 through 20.) The bits correspond to the counters as follows: Bit 08 = counter 0; bit 09 = counter 1; bit 10 = counter 2; bit 11 = counter 3.

This bit determines whether BCD or binary format is used. Bit 15 = 0 Indicates all values in the BTW file and the BTR file will be in binary. (Diagnostic byte (word 1) is always BCD.) Bit 15 = 1 Indicates all values in the BTW file and the BTR file will be in BCD

Enables outputs.

 Bit 00 corresponds to output 0, bit 01 to output 1, etc. Outputs must be enabled before they can be turned ON. Bits must be set (1) before the output can be turned on. bits 0815 Output forcing bits. Setting a bit to 1 allows the output to be forced. Bit 08 corresponds to output 0, bit 09 corresponds to output 1, etc. Outputs must also be enabled
