IO OB Output Bit OB n,ex Usage OB n ... Arguments specified with an implicit, comma-separated order Description The OB command allows variable control of an output bit based on logical expressions. The OB n, logical expression command defines output bit i as either 0 or 1 depending on the result from the logical expression. Arguments Argument Min n 1 n 1,000 ex N/A Max 4 6,999 Default 0 N/A N/A N/A Resolution Description Notes 1 Output bit specified 1 Modbus output bit specified See Remarks If ex is true/non-zero, set output to 1. If ex is Expression Expression that defines status of output false/zero, set output to 0 Remarks An expression is any valid logical expression, variable or array element. Any non-zero value of the expression results in a one set to the output bit. n0 = (SlaveAddress*10000) + (HandleNum*1000) + ((Module-1)*4) + (Bitnum-1) Slave Address is used when the ModBus device has slave devices connected to it and specified as Addresses 0 to 255. Please note that the use of slave devices for modbus are very rare and this number will usually be 0. HandleNum is the handle specifier where A is 1, B is 2 and so on. Module is the position of the module in the rack from 1 to 16. BitNum is the I/O point in the module from 1 to 4 Examples 'Galil DMC Code Example OB 1, pos;' If pos<>0, Bit 1 is high. ' If pos=0, Bit 1 is low OB 2, @IN[ 1] &@IN[ 2] ;' If Input 1 and Input 2 are both high, then ' Output 2 is set high OB 3, count[ 1] ;' If the element 1 in the array is zero, clear bit 3 OB n, count[ 1] ;' If element 1 in the array is zero, clear bit n 'Galil DMC Code Example 'Toggle digital output 1 OB 1,@COM[ @OUT[ 1] ] & 1;' read current state of output 1, take the bitwise complement, mask out bits. ©2015 Galil Motion Control.
