Technical Specifications
Calculating the address of last PID loop on the second expansion module SM231-7TF.
According to the above statement: S=1, C=7
A Address, A=2048 + 1 * 256 + 16 * 7 = 2416
X Address, X=2048 + 1 * 256 + 12 = 2316
Y Address, Y=2048 + 1 * 256 + 13 = 2317
Set or read out the parameter values according to the following parameter address descriptions:
VW2544 //Set temperature
VB2546 //Control word (parameter self-adaptive, bipolar output)
VW2548 //Pulse output period
VW2550 //Kp
VW2552 //Ti (s)
VW2554 //Td (s)
VW2416 //Actual temperature
VW2418 //Status word
VW2420 //PID analog output
V2316.7 //Positive pulse output
V2317.7 //Negative pulse output
Do not use the V memory occupied by the PID module you use when program other block for
sake of PID module normal usage. You can call the specific parameter configuration library of
SM231 PID.
Address the module occupied in slot 0: VW2048 to VW2298
Address the module occupied in slot 1: VW2304 to VW2554
Address the module occupied in slot 2: VW2560 to VW2810
Address the module occupied in slot 3: VW2816 to VW3066
Address the module occupied in slot 4: VW3072 to VW3322
