1、如何计算 BK5200 输入输出字节数? 答答: : 以下图配置为例 (3) KL 1002 (2 channel 24Vdc discrete input terminals) (1) KL 2002 (2 channel 24Vdc discrete output terminal) (2) KL 2114 (4 channel 24Vdc discrete output terminals) (1) KL 1501 (High speed Up/Down counter) (1) KL 4002 (2 channel 0-10V analog output terminal) (1) K

2、L 3062 (2 channel 0-10V analog input terminal) (1) KL 9010 (end terminal) 输入字节数的计算方法: Rx (bytes) = (IN1 + IN2 + INn ) / 8) (+1 如果有余数) + 1 status byte VariableVariable TerminalTerminal TypeType # of produced # of produced bitsbits Analog orAnalog or DiscreteDiscrete IN1 terminal 1 KL1002 2 bits discr

3、ete IN2 terminal 2 KL1002 2 bits dicsrete IN3 terminal 3 KL1002 2 bits discrete IN4 terminal 7 KL1501 40 bits analog IN5 terminal 9 KL3062 32 bits analog Rx (bytes) = (IN1+IN2+IN3+IN4+IN5)/8) +(1 if a remainder exists) +1status) (2+2+2+40+32)/8+(remainder exists so +1) + 1status) Rx = 11 bytes 输出字节数

4、的计算方法: Tx (bytes) =(OUT1 + OUT2 +.+ OUTn) /8) (+1 如果有余数) VariableVariable TerminalTerminal TypeType # of consumed # of consumed bitsbits Analog or Analog or DiscreteDiscrete OUT1 terminal 4 KL2002 2 bits discrete OUT2 terminal 5 KL2114 4 bits dicsrete OUT3 terminal 6 KL2114 4 bits discrete OUT4 term

5、inal 7 KL1501 40 bits analog OUT5 terminal 8 KL4002 32 bits analog Tx (bytes) = ( OUT1+ OUT2 + OUT3 + OUT4 + OUT5) / 8) + ( 1 if a remainder exists) (2 + 4+ 4+ 40 + 31) /8 ) + ( remainder exists so + 1) Tx = 11 byes The following is a tabular display of the Rx string: BytByt e # e # Data information
