ElmoMC Multi-Axis Motion Controller-Maestro - Manual (Page 225)

Parameters:
coilAddress – coil (discrete output) address (range: 1 - 65536)
Returns: Content of selected coil (range: 0-1)
Example:
masterObj.readCoil(10)
Function using For command interpreter only
2. int retVal = readCoils(int startAddress, int ::iStaticArray , int num)
MODBUS function code 01.
Reads the status of the contiguous discrete outputs (coils, 0:00000 table). Up to
2000 coils.
Parameters:
startAddress – start coils address (range: 1 - 65536)
iStaticArray – static integer array which will contain the data read
num - number of contiguous coils to be read (range: 1-2000)
Returns: 0 on success or error code.
Example:
masterObj.readCoils(10, ::iStaticArray , 40)
3. intVal = writeSingleCoil(int coilAddress, int val)
writeSingleCoil(, int val)
MODBUS function code 05. Sets a single discrete output variable (coils, 0:00000 table) to
either ON or OFF.
Parameters:
coilAddress – coil (discrete output) address (range: 1 - 65536)
val – new coli value (0 or 1)
Returns:.
0 on success or error code
Example:
masterObj.writeSingleCoil(10, 1)
