相位通信PCOM功能塊，在固件1.30及更高版本，每個(gè)循環(huán)一個(gè)實(shí)現(xiàn)更高級(jí)別通信的基礎(chǔ)設(shè)備，如運(yùn)行批處理管理的PC軟件程序。當(dāng)控制器配置為結(jié)構(gòu)化的，使得邏輯操作在小相位操作，PCOM塊便于控制整個(gè)相位的邏輯之間的接口批處理的操作和執(zhí)行每個(gè)階段的控制邏輯。
PCOM塊執(zhí)行的邏輯詳見圖3-1中的布爾形式。網(wǎng)絡(luò)通信可以是Modbus或LIL（本地儀表鏈路）。
詳細(xì)信息在網(wǎng)絡(luò)通信中列出部分在ODC或ODS中配置的循環(huán)
循環(huán)的功能塊確定Modbus中的狀態(tài)字和狀態(tài)線圈映射。通信狀態(tài)表示為圖3-1，下一頁，使用所示符號(hào)
在下面Modbus狀態(tài)映射到線圈和LIL中映射到兩個(gè)16位狀態(tài)字的狀態(tài)，如圖所示在下面三個(gè)全局通道用于發(fā)送兩個(gè)狀態(tài)字和一個(gè)1-7的整數(shù)值表示PCOM塊的狀態(tài)：1=中止，2=完成，3=保持，4=運(yùn)行，5=INTRLK，6=就緒，7=應(yīng)急或。第一個(gè)通道的位置為：使用LIL CHAN參數(shù)配置，由LIL映射表中的通道z表示。
讀/寫狀態(tài)R 0W1W0
開始讀取狀態(tài)運(yùn)行R1/0每個(gè)通信狀態(tài)被讀取為1或0。使用Modbus，寫入1（W1）或0（W0）將影響
圖3-1中相關(guān)邏輯定義的通信狀態(tài)。W1或W0相當(dāng)于或上的掩碼使用LIL命令屏蔽。除OK、RD、RN和HE外，所有未配置的輸入將被視為低（0）其將被視為高（1）。三種輸出狀態(tài)，EO（“EMERG”）、IK（“INTRLK”）和FD（“失敗”）可配置為優(yōu)先級(jí)0-5。這將影響閃爍等。如前所述，其他控制器狀態(tài)條件。這些狀態(tài)也有未確認(rèn)位，如狀態(tài)字2.條件中所述可以通過使用本地面板確認(rèn)按鈕或通過寫入來確認(rèn)需要確認(rèn)的
單個(gè)未確認(rèn)位或未確認(rèn)PCOM位。
The Phase Communication PCOM function block, in
firmware 1.30 and higher, is available on a one per loop
basis to enable communication with a higher level
device, such as a PC running a batch management
software program. When the controller configuration is
structured such that logic operations are partitioned in
small phase operations, the PCOM block facilitates the
interface between the logic controlling the overall phase
operations for the batch and the logic performing the
control logic for each phase.
The logic performed by the PCOM block is detailed in
Boolean form in Figure 3-1. Network communication
can be either Modbus or LIL (Local Instrument Link).
Details are listed in the Network Communications
section. The LOOP # configured in the ODC or ODS
function block for the loop determines the location of
the status word and the status coils in the Modbus
mapping. Communication states are represented in
Figure 3-1, on the next page, using the symbols shown
below. Modbus states are mapped in coils and LIL
states mapped into two 16-bit status word as shown
below. Three global channels are used to send out the
two status words and an integer value from 1-7 that
represents the status of the PCOM block: 1=ABORTED,
2=DONE, 3=HELD, 4=RUN, 5=INTRLK, 6=READY, 7=EMER OR. The location of the first channel is
configured using the LIL CHAN parameter, represented by channel z in the LIL mapping tables.
Read/Write States R 0
W 1
W 0
START Read States RUN R 1/0
Each communication state is read as a 1 or 0. Using Modbus, a write of a 1 (W1) or a 0 (W0) will affect the
communication state as defined by the associated logic in Figure 3-1. The W1 or W0 is equivalent to a Mask ON or
a Mask OFF using LIL commands. All unconfigured inputs will be treated as low (0) except OK, RD, RN and HE
which will be treated as high (1). Three of the output states, EO (“EMERG”), IK (“INTRLK”), and FD
(“FAILED”) can be configured for priorities 0-5. This will affect the flashing, etc. as previously described for other
controller status conditions. These states also have unacknowledged bits as detailed in status word 2. Conditions
that require acknowledging can be acknowledged by either using the local faceplate ACK button or by writing to
the individual not acknowledged bit or the Not Ack’d PCOM bit.
