SF_ES
PE
• This FB monitors electro-sensitive protective equipment (ESPE). The function is the same as that of
the SF_EmergensyStop instruction. As soon as the
S_ESPE_In
input is set to FALSE, the
S_ESPE_Out
output is set to FALSE. If the
S_ESPE_In
input is set to TRUE and the function is
reset, the
S_ESPE_Out
output signal is set to TRUE. Enabling the reset is determined by the defined
S_StartReset
,
S_AutoReset
, and
Reset
inputs.
• If
S_AutoReset
is TRUE, the confirmation operation is performed automatically.
• If
S_AutoReset
is FALSE, a change to TRUE in the
Reset
input must be made for enable confirma-
tion.
• If
S_StartReset
is TRUE, the confirmation operation is performed automatically when the Safety CPU
Unit first starts.
• If
S_StartReset
is FALSE, a change to TRUE in the
Reset
input must be made for enable confirma-
tion.
• Activate the
S_StartReset
and
S_AutoReset
inputs only when you can ensure that no hazardous
state will occur as the result of starting the Safety CPU Unit.
• ESPE must be selected for the category that is required according to product standards IEC/EN
61496-1, IEC/EN 61496-2, IEC/EN 61496-3, and EN ISO 13849-1.
