    PRP Series Programming Manual Execution Errors Overview An <error/event number> in the range [ -299 , - 200 ] indicates that an error has been detected by the instrument’s execution control block. The occurrence of any error in this class shall cause the execution error bit (bit 4) in the event status register (IEEE 488.2, section 11.5.1) to be...
  • Page 83 REMOTE CONTROL Indicates that a command is not executable E-201 Invalid while the device is in local due to a hard local while in local control (see IEEE 488.2, 5.6.1.5); for example, a device with a rotary switch receives a message which would change the switches state, but the device is in local so the message can’t be executed.
