Description
Selects whether clock data received in SECS message is of ASCII12Byte or ASCII16Byte.
This setting is reflected in the equipment variable TimeFormat.
Configure the register to notify the programmable controller CPU about the received clock data. This setting is linked to
the state variable Clock. To convert received ASCII data to numerical data that the programmable controller CPU can
process easily, select the "Store Clock Data In DATE Format" checkbox and select either "DATE-A" or "DATE-Q".
To lock the update of clock data, a clock-data lock relay is used, and this relay is turned ON from the Programmable
Controller CPU.
Configure the relay to request sending of an S2F17 (date and time synchronization request) to the SECS/GEM
communication software from the programmable controller CPU when there is a time synchronization request from the
equipment to the host.
It is necessary to select the checkbox in addition to "Request From Device To The Host (S2F17)" of Advanced
Settings.
Configure the relay for the SECS/GEM communication software to notify the programmable controller CPU of receipt
of clock data when the host request time synchronization to the equipment.
