Bit Lamp | Operates by combination of digital tags. Lamp state is changed according to data value or bit combination. | |
Word Lamp | Changes the lamp state by tag value or bit combinations. | |
Lamp states | Changes the lamp state with various methods, according to each lamp type. | |
Changing States with Bit Lamp | Change State by Bit Combination | Each digital tag composes each digit of the binary number. The state of data is defined according to the combination of each digit.  E.g.) If DIGITAL1 = 0, DIGITAL2 = 1, DIGITAL3 = 1 and DIGITAL4 = 0, they indicate 0110 in binary. Since it is equal to “6” in decimal, the ‘State 6” is displayed. You can use maximum 16 states with this option. |
| Changes State by Bit | Each digital tag represents a single state. If all digital tags’ values are “0”, “State 0” will be displayed. If the DIGITAL4 = 1, the “State 4” will be displayed. When multiple tags are set as “1”, the priority goes to the state with the lower number. You can use maximum 5 states with this option. |
Changing States with Word Lamp | Change State by Bit Combination | Displays the state with a single analog tag. Maximum 256 states can be displayed. |
Change State by Bit | Since an analog is composed of a word, it is possible to display the states with 16 bits. It indicates that a word can display 17 states. Only one bit has to be turned ON at a time. If any other bit is ON simultaneously, the priority goes to the less significant bit.   E.g. 1) If the value of an analog tag is 3(0000 0000 0000 0011), State 1 and 2 are supposed to be ON. However, since State 1 has higher priority, the State 1 is ON.  | |
