Pfaff 3588-04/020, Instruction Manual, Page: 152 / 196

14 - 2
Controller
Diagnostic function 31-38
Indicate number of the node 1-8 to be monitored at the diagnostic LEDs DO8-DO1.
Indicate status of the node 1-8 at the diagnostic LEDs DI8-DI1.
DI8 = amplifier error (short-circuit)
DI7 = -
DI6 = -
DI5 = Waiting for remote input object (receive status)
DI4 = Transmitting output object (transmit status)
DI3 = -
DI2 = CAN node does not reply (timeout)
DI1 = CAN node is active
Error-free state: LED DI1 on,
LEDs DI2, DI3, DI6, DI7 and DI8 off,
LEDs DI4 and DI5 blink at a high frequency.
Diagnostic function 98
Indicate numbers of the active CAN nodes at the diagnostic LEDs DO8-DO1
(active nodes = D08*128 + D07*64 + D06*32 + D05*16 + D04*8 + D03*4 + D02*2 +
D01*1)
Indicate status register of the CAN controller at diagnostic LEDs
DI8 = -
DI7 = -
DI6 = -
DI5 = Waiting for remote input object (receive status)
DI4 = Transmitting output object (transmit status)
DI3 = -
DI2 = CAN controller status: Halt
DI1 = CAN controller : Reset
Diagnostic function 99
Indicate the number of the node at which an error last occurred at the diagnostic LEDs
DO8-DO1. (No. = D08*128 + D07*64 + D06*32 + D05*16 + D04*8 + D03*4 + D02*2 +
D01*1)
Indicate status at diagnostic LEDs DI8-DI1.
DI8 = amplifier error (short-circuit)
DI7 = -
DI6 = -
DI5 = Waiting for remote input object (receive status)
DI4 = Transmitting output object (transmit status)
DI3 = -
DI2 = CAN node does not reply (timeout)
DI1 = CAN node is active
Error-free state: LED DI1 ein,
LEDs DI2, DI3, DI6, DI7 and DI8 off,
LEDs DI4 and DI5 blink at a high frequency.
