Status Monitor by Diagnosis
Explanation of Status Output
The HR6S diagnoses and monitors connected devices, and can output the results to the Tr output (not safety-related).
The status monitor outputs a pulse signal instead of I/O.
The length of the diagnostic bit sequence output from status output Z1 is 2 s. The configuration is a 10-bit signal where each bit is 200 ms. The first
4 bits (0010) are the start codes that represent the start of the bit sequence. The next 6 bits are a diagnostics code that indicates the status of the
HR6S.
The cycle time (scan time) of the task that executes the program must be 50 ms or less for the bit sequence to be detected correctly. A ladder
program for decoding by PLC is provided. (Contact IDEC regarding PLC ladder programs for IDEC FC6A PLC or other manufacturer's PLCs.)

*6) When the switch is used to start, start is triggered at the falling
edge of the start signal. The safety-related input must be activated
Yes
for a period of at least 80 ms.
Yes
*7) When the startup test is set to "Yes", the safety-related input must
be disabled and then re-enabled before the safety-related output
Yes
can be turned on. Normally, it is used to monitor guards. Even if
No
the automatic start mode is selected and the guard is closed, after
power is turned on, the guard must first be opened and closed.
No
*8) Start input Y2 watches the pulse superimposed on the output from
No
Y1 to check that there is no short-circuit between other input wires
and power supply wires, and then starts. When 24V signals are
No
input to Y2 from PLCs, select "Dynamization - No".
Note 1: If the status of the HR6S changes during the output
of the bit sequence, it will be sent in the next
sequence. Therefore, the maximum delay in status
output for a change of status is 4 s.
However, if the running bit sequence does not last
until the next sequence starts (if status changes
occur within 2 s), it will not be sent in the next
sequence.

Note 2: Turning off the power connected to the HR6S safety
module can cause the ladder program to detect
incorrect status information.
