CB_CL_CNTL is given by CB_SELECTED and close command from PLC/panel/remote system
and close enable signal which made in internal logic. In addition, CB_CL_OUT is given for
device control. It is kept till the timer "CBCLP" count up in case of [CBPM] "Var", or till changed
device status. CB_CL_OUT must be assign to BO by PLC function.

CB pulse mode [CBPM] is as follows:
The pulse mode can be set to "Fix" or "Var". When "Fix" selected, the control output turns OFF
automatically after the device responds. If the device does not respond, the control output turns off
after the setting time of CB response check timer CBRSPT has passed. When "Var" selected, the
control output is ON during the setting time of CBCLP or CBOPP. (For the setting range, see
2.6.2.7.)
