9. Operating system diagnostic messages
610
Operand Event
ID17 –
ID18 –
ID19 There is an interrupt overload. One or more interrupt function blocks are being used, and the interrupt
function block sequence is overloading the easyE4's controller. Not all interrupt function blocks can
be run correctly.
Additional diagnostic messages for the expansion devices can be assigned to dia-
gnostic operands ID25 through ID96 based on the relevant device characteristics.
Transistor output example
Transistor outputs on expansion devices EASY-E4-DC-8TE1(P), EASY-E4-DC-16TE1(P)
When there is a short circuit or overload at an output, the DIAG diagnostic message
can be applied to a diagnostic operand. This means that when the event occurs, the
operands will assume a state of 1.
Example Analog expansion device
Name on Event
device
DIAG General diagnostic indicating that a diagnostic event is present
DIAG 1 Current input overloaded (current greater than 23 mA), excessive voltage
DIAG 2 Analog output overloaded, excessive current, load too small
Open wire at at least one current input (I < 4 mA)
DIAG 3 The measuring range has been physically exceeded at an input
DIAG 4 The measuring range has been physically fallen below at an input, e.g., the current is < 4 mA for a
measuring range of 4–20 mA.
Temperature expansion example
Name on Event
device
DIAG General diagnostic indicating that a diagnostic event is present
DIAG 1 Configured measuring range exceeded at at least one temperature input, or connection cable dis-
continuity
DIAG 2 Configured measuring range fallen below at at least one temperature input, or a short-circuit
has occurred
